2005 Grand Caravan...power locks will not unlock or lock by either the remote or the door switch. I saw no fuse blown under the hood but could not ID the relay.

I had the same problem, but not till the car was 2 years old.

Pull the OID fuse, count to five and put it back in. If that fixes your problem (temporarily), ask the dealer to look up the TSB that reflashes the body controller to an updated software level. Cost me $70, but no problems since (6+ weeks).

Like Bill says, pull the OID fuse and reset it. I've done this numerous times without a problem. I also discovered that the problem only occurs when I use the remote to LOCK the doors. If I manually lock the driver's door when I exit the van, I do not have the problem. Unlocking the doors with the remote has never caused the problem, only locking them with the remote.

My dodge caravan door locks stop working. I looked for the fuse but the book is vague on the location of the fuse or relay. I looked under the steering column but I could not find the box. Can anyone tell me what fuse or relay to pull to reset the system.

My 2005 caravan's power locks quit working. I've looked for the OID fuse, but cannot find it. All the fuses I've looked at have a number printed on them, I have no idea which one to unplug, wait for 5 seconds, then reinsert. Help!!!!

Look on under side of fuse box lid for markings for the fuses its there towards bottom left if you are standing on driver's side of the vehicle. Fuse box is under the hood on drivers side not inside of van.

Reply #9 Cassi (68.223.143.211) - Mon May 26 10:47:11 2008

Wayne - It's a 20 amp fuse in the middle on the left. Look at the top of the fuse box on the inside of the cover. You will see the diagram for which fuses are where.

Thank you everyone! You just fixed my problem.

My Dodge Grand Caravan is a 2003. My front door locks work fine - it's just the two side rear doors that "try" to lock or unlock when you push the button = but it can't. So I found the IOD and in my van it is a 15 amp. Pulled it, waited, put it back. Still works the same as before. Any ideas?

YOU PEOPLE ROCK!!

I have a 2005 Town and Country with the same problem. (Well, IT USED TO HAVE THE SAME PROBLEM, BUT I FIXED IT! I FIXED IT!)

Prior to google searching and finding this thread, I stopped at two car parts dealers and they looked at the situation. One suggested the fuse may be the problem, but neither store could identify which fuse. One place even tried to look it up in their reference materials...all to no avial.

So per your suggestions, I pulled the 20 AMP IOD fuse, counted 5 seconds, plugged it in and now my locks work! Guess I can cancel that appointment at the dealership tomorrow!

Is a recall in order? It is a safety issue in that I could not lock 1/2 the doors on my car, not while driving or parked. I'll investigate and let you know!

Im happy with the door lock solution but this car is crap. Its two years old and here is my list of failures.. please list yours.

1. Both sliding door locks failed/lock mechanism broke

2. washer fluid pump failed

3. Washer fluid tank sprund leak

4. water pump failed

5. brakes wear unevenly and need replacing far too soon

6. frame came slightly bent causing it to be impossible to align vehicle correctly

7. computer needed update after 50K miles for some sort of transmission control issue. Wow a computer needed an update after 50K miles for this??

8. Catalitic convertor failed

9. Heater resistor failed 2 times

10. Head gasket failed

11. Fuel gauge sending unit failed- always indicated 1/2 full- this was real fun when I stopped in the middle of the interstate

12. door locks will not lock- fixed by this forum

13. There are others I cant remember now.

Oh by the way.. when purchased the dealer offered lifetime oil changes at no cost. Then, the dealer went bankrupt and the new dealer decided not to live up to the contract requirements of the old dealer. How nice.

Granted all of my issues short of loss of free oil changes promised were covered under warranty. I have a personal relationship with the shuttle driver at my dealer

Wow what a vehicle!! Im selling mine if any one needs one for parts.

Thanks for letting me vent about this piece of crap.

This same thing is happening to me. We have a 2004 Ford Freestar. We have power sliding doors and they don't always lock/unlock. We have been pulling the lock up or pushing it down. Took it in and they say that it is needing some kind of motor because it is completely shot. It is a 500 dollar job ( of course @@) They don't realize it works some of the time. Would this work for my van as well? I don't think it needs a motor as the doors open.

tia!

I have a 2006 caravan and the IOD fuse blew out and when I tried to replace it, the new fuse blew out immediately. I have an electrical short on the IOD circuit.The following systems do not work because I can not get a fuse into the IOD circuit without it blowing out immediately. The keyless entry remote, any button, the door locks don't work, even manually from the inside button, sliding power doors, both sides, power lift gate, factory radio / DVD player, visor lights, alarm to let you know your key is in the ignition when you open your door, and sometimes when I turn off the key off and take it out of the ignition some of the ignition dash lights will stay on { check engine light and oil light ect. }If I put the key back in and turn it off and on the dash lights will eventually go out. I have owned this van since it was brand new and no modifications of any kind have ever been done do it, 100% stock. My van is less than 1000 miles out of warranty 35, 850. Anyone ever had this problem or a similar one? Or know where I can get some help with this?

2005 Chrysler Town & Country Touring

Bought used 6 months ago, this is first issue. Pulling IOD for 10 seconds reset it perfectly. Is there any pattern I can expect - like this happening only in super hot weather or something?

BTW, be sure power is off & key out of ignition when pulling any fuse.

Reply #30 Cathy (71.205.143.7) - Sun Aug 3 15:48:30 2008

When I talked to the dealership about the lock issue, they said to expect that my fix-it job will only be a temporary fix and that I needed upgraded software. ($89) I'm taking my chances.

In the meantime I'll be looking up how to request a recall. Seems like if their computerized system needs an upgrade that that should be a recall deal as it is not wear and tear that is causing a malfunction. It is a design defect.

My 05 caravan just rolled over 44k miles and guess what. Yup the door locks stopped working. Having worked with computers for 20 plus years it smelled like a computer computer problem.

Before I got into a huff and started to jumping thru flammimg hoops with the dealer I checked all the fuses and then disconnected the battery for a few minutes and hay, the locks started to work again.

This fix was short lived as the problem came bach within a day.

Tonight I've read allot of internet posts from 05 and 06 caravan owners with the same problem. There does not appear to be a solution to this problem. The problem appears after 44k miles.

Some have had the BCM re-flashed and in some cases replaced and the problem comes back. It sounds like Dodge has a bug in their BCM firmware that has not been fixed. This bug gets out of warranty units back to the dealer for a snake oil computer flash fix that costs $130 a wack and it takes 10 minutes to do. Sounds like a cash cow to me. [If mileage greater than 44, 000 miles] [then door locks stop working.] There is a safety issue and a customer satisfaction issue here that needs to be fixed.

I 'm looking forward to 54k miles when I need to re flash the computer so the transmission will shift. And at 64K miles when the buy new car light goes on. Yes I too have had the brake rotors, AC compressor and EGR replaced. It sounds like I've gotten off easy compaired to some.

This is my 3rd caravan. I've had an 84, 91 and this 05 and this one is my last caravan. I really like this this caravan and the others I've owned but the cost of ownership is just too high and long term quality and reliability is just too low.

My other car is a 1990 Honda CRX si with 230k miles. I see no reason why this car won't make it to 300k miles. Have you ever heard of a caravan living 300k miles? I don't think so.

It's too bad that people, probably children will have to die before this is fixed.

If anyone has a real fix for this door lock problem please drop me a line.

My locks stopped working last week. I pulled the IOD fuse as this forum suggested (THANKS BTW) and plugged it in and my locks, the auto-locking door feature at 20 mph and my key-chain lock/unlock are working again.

This is a huge problem, there are alot of us having issues there are currently no recalls (via checking up with dodge) so this is my recommendation; email them.

Is is worth 3 minutes of our time to let them know that as a collective us 2005 dodge grand caravan users are having problems, yes! I emailed and I hope you will too.

Reply #37 Alan (65.87.134.132) - Sat Aug 9 16:50:14 2008

Short Temporary Fix: Pull IOD fuse. This can work for a good while the first time, gradually it'll progress to needing almost every time.

Better Temporary Fix: Disassemble your key. The back pops off to replace the battery, there is a slot near the metal of the key to help pry it off. Once there, discharge yourself to the ground screw of an outlet then take out the small printed circuit board. The side under the buttons has little gold contact circles, put a small piece of tape over the one under the 'lock' button. Reassemble your key. This forces you to lock with the inside door button. Tape and hide a key on the underside of the van somewhere, you can lock the keys in much more easily, but at least the van will unlock now. Was requiring IOD reset almost every time, now it has easily gone 20 or 30 times lock/unlock without, but the key can only unlock, still far more convenient than resetting all the time.

The problem and real fix.. Does appear to be related solely to locking with the key. Most likely there is a switch on each lock to let the computer see that the doors have locked. Over time they can get dirty or oxidize, just like a door/interior light switch can and not turn on the interior light when a door opens. When the computer tries to lock the door and doesn't see a good switch close, it likely disables itself so it doesn't burn up the door lock motors. This is a good thing, but if you have a dirty switch it means the door lock computer will disable itself often. Likely the BCM code update makes it more tolerant of a dirty switch, while not really addressing the real problem. Clean the contacts on all the door lock switches and you'll likely get 50K more miles of good service. Clean and use a good conductive contact lube on them and you'll likely never have a problem again with them. Note that this is cheap for DIY but labor intensive since you'll want to do every lock, and would be nuts at a dealer due to labor.

I just taped the key for my mother's van. Next time I go up there I'll do the real fix, and report back on the results. This could also be related to the common automatic side door failure that she has, the wires for the side door locks/switches are in that wire bundle that is the likely failure point..

Reply #38 Alan (65.87.134.132) - Mon Aug 11 10:20:36 2008

Ok the tape on the key doesn't work for long. Appeared to work, but eventually the computer will still stop locking the doors.

Very likely this is a bad switch or wiring, and the computer can't see that a door did lock, and stops trying to avoid burning out the motor. I'll do what is likely the real fix in a week or two, and report back..

Pulling the 20 amo IOD fuse on my 2005 Town & Country fixed this for me too! Is there an easy and cheap permanent solution? My wife wants this fixed so that it stops happening.

We have a 2005 Grand Caravan and I was in an accident in 2006.

They replaced the computer. Our problem is a bit more complex. when driving the lights flash off and on , the speedometer jumps all over the place, and the clock changes time. This did not happen until after the accident (NMF) and the dealer has told mne from the beginning that they can't find a problem and the warranty is no longer good. We are trying some of the suggestions all of you made... WISH US LUCK!!!

Reply #41 Jeff (155.77.200.253) - Mon Aug 18 08:55:08 2008

We had this problem with our 2005 Grand Caravan about 2 months ago. I thought it was a fuse since everything else on the vehicle worked. I pulled most of the fuses to check for blown ones since there was not one specifically labeled for the door locks. I must have pulled the IOD one because the locks worked then. Now, the locks are not working again, so I will pull that fuse again to see if it fixes the problem. If it gets to the point where it is happening every time you need to use the car, I will have to break down and pay for the real fix at the dealer.

This should be a recall issue if it is happening to just about everyone who owns this type of vehicle. What a joke.
