power locks will not lock or unlock

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.

Have the same issue with 2005 Grand Caravan power door locks; glad to have found this site. Will pull the IOD fuse tonight and report back.

I suspect, though, that my problem is the wiring harness on the (manual) driver's side sliding door. The "caterpillar track" (what's the right name for this part?) that the wiring harness travels in has been cracked and essentially self-disintegrated for months. We use that door now only very infrequently when we forget, but I suspect that if a damaged wire/faulty door sensor signal can cause this problem, then that is probably the source.

I'm an electrical engineer and pretty handy, so I know how to repair wires if I can find the fault.

Anyone have any thoughts on

- how to diagnose the fault

- where to get replacement "caterpillar tracks"



**/**/** **:**

Pulling the fuse worked as expected based on the forum. Locks are still working two days later. I've never been so satisfied to see them go up and down when I press the buttons, as I am now. Nice.

I have had this problem with my Chrysler 2005 Town and Country for around 3 years now. Initially the IOD pull would do the trick for a couple months, and then it would have to be pulled again to continue the fix. However over time the length of the IOD "fix" has gotten shorter and shorter. Now I am lucky if it lasts a couple of days. My car has other electrical issues as well (gas gauge sometimes goes to empty and then back up again, O2 sensor turns on check engine light but then it goes back off again, and have been through about a battery every year and a half).

I think Chrysler has a pretty serious issue here. It is stunning to me that there is not even a pay fix for this, let alone the fact it appears it needs to be a recall item based on volume of issues.

Has anyone had luck with the BCM update?

Tried pulling the IOD fuse on my 2002 Dodge Grand Caravan. Passenger rear slider still won't unlock, either manually or with power lock button. Should the ignition be on when pulling the fuse?

My 2005 Grand Caravan power door locks quit working yesterday at 49, 991 miles. I found this blog today and like everyone else, pulled the IOD fuse and reset the system. I also polished the fuse contacts with steel wool before reinsurting back into the fuse panel. The locks now work. I checked each door lock manually to make sure they are working freely--they are. Both sliders work well too! I am a former ASE Master Automotive and Diesel technician, but out of the field for a few years. I will dig into this issue more if my power locks quit working again.

Also, I do not use a remote key, but rather a grey sentry key. Remote keys ensure your vehicle is stolen if someone gets your keys as the remote leads them to your vehicle. Just a pet peave with me.

Same as everyone else, 45K or so miles, passenger doors stopped reliably locking/unlocking. The do TRY but don't actually make it. I changed the battery on the car and it worked for a while, but it's not working again. The front doors and the rear door still unlock fine. I don't mind locking manually, but I've gotten spoiled by having the doors open for me when I have my hands full of grocery bags. I'll try the fuse, but it sounds like all that does is reset a circuit in the computer. The real problem lies either in the programming or the locks installed on EVERY side door in these cars is inferior to the other locks. Doesn't sound likely to me. Thanks for the info, everyone.

Thank author of this post/comment"Thanks!"

Thanks for the help! This did the trick.

To Comment #333 Neoen: This is a normal feature for this vehicle(and most others I've had). Push unlock once for driver's side door unlock, push it again to unlock all doors. Nothing's wrong with your system.

My 2005 Chrysler Town & Country has been experiencing the same problem with the locks not working correctly for about a year. I have been using the IOD fuse reset trick since I found this thread about 8 months ago. Thank you all.

The reset is always temporary, lasting anywhere from a day to a few weeks.

One big safety concern is that when the locks aren't working properly, the rear hatch is unlocked when the engine is off and cannot be locked manually. When the engine is on, the hatch is locked.

Has anyone found a permanent fix for this problem? Maybe if enough of us report this problem to Chrysler, they will do a recall, as this is a safety concern.

Thank author of this post/comment"Door Lock Actuator"

Hi everyone,

I have a 2005 Dodge Caravan. Like most folks here, my locks conked out right after the 5 year warranty expired.

Anyway, the IOD fuse reset is a temporary solution. It seems as if the problem is the door lock actuator failing. If one of the actuators fail, all 4 locks are disabled. You can usually tell which actuator is failing by trying to manually lock/unlock each door - the one which fails would be difficult to unlock or lock.

The BCM update or replacing the BCM will not address this issue. It seems to increase the tolerance on the actuator fail setting, which means that the problem will recur once the actuator fails completely.

So there are 2 solutions:

Replace the actuator - I bought mine from RockAuto for $40


Open the actuator and replace the motor - the motor is about $2, but it takes a bit of handiwork to remove the gears from the old motor and install on the new motor.

Take care,

Thank author of this post/comment"More bad door locks..."

Bought a 2004 Dodge Caravan SE. Drivers side power lock switch does not lock or unlock the rest of the van. Passenger side locks / unlocks all locks. Tried replacing switch, same symptoms. Tried IOD fuse pull and battery NEG disconnect. Neither seemed to help. When I was replacing the switch (from the junkyard), The locks work via the driver switch when I connect (open circuit) or connect (closed circuit) the switch. If I leave the switch connected and try to utilize it, I get nothing. Jumpered the harness with a wire, get a response with that. Did I buy a bad switch at the junkyard? How hard is it to add RKE (Remote Keyless Entry) to the SE model (I don't know if the module is present or not). Thanks for listening!

Hello everybody,

We also have a 2005 GC SLX...And for the last 3 years we've been having problems with the sliding door on the passenger side that doesn't open or close (it tries to), with all the locks that don't lock or unlock automatically anymore (only the one on the trunk), and the window on the passenger side that doesn't open.

Today I did a search on this site and found out that they have a post for each of the problems I have on my van! That means there is a lot of people with the same problems we have! How come Dodge never did a recall for all these problems?

In one of the posts someone posted a link for the site where we can all file a safety complaint, and maybe then Dodge will have to do a recall.

Other posters taught how to fix the sliding doors problem by mending or changing the wires. Someone even posted a link to a website that sells the replacement parts for the sliding door (trademotion...but I haven't check it yet).

I'm posting the link about the sliding doors. For the complaint web site, try safecar dot gov and click on vehicle owners, and on the menu go to file a complaint. I haven't done that yet, but I will.

I hope this was helpful to you all.

Hello all,

We also have problems with all our door locks, and some mechanic told us that we would have to take the car to the dealership to reset the chip. We didn't do that because we heard that would cost a lot of money (400 or so).

The interesting thing is that when we had to replace the battery, the door locks started working again, but it did not last long (less than a week). I think that if you disconnect the battery it will reset the door locks, but they won't work for long time.

I'll try resetting the IOD plug and see what happens...

I'll keep you posted.

Have a great day!

I have a similar issue but mine is that only one door will not unlock/lock. I can't open the sliding door on the right side of the van. It is now permanently locked.

Any ideas??

Thank author of this post/comment"Dodge Caravan locks do not lock"

This IS a safety issue. I contacted my local dealer by e-mail and by phone and the owner would not get back to me.

Pulling the IOD fuse is a temporary fix.

It lasts about a week.

So this is what everybody should do and it is free.

Call the National Highway Traffic Safety Administration (U.S. DOT)

at : 1-888-327-4236.

They will take down your statement (have your v.i.n # ready.

And a few weeks later you will get a letter from them.

This is serious. Make the call. Thanks

I filed a safety complaint with the National Hwy Traffic Safety Admin (DOT). If everyone does this, maybe something will be done.

You will need to provide your VIN for the complaint.

I had been having the same lock problem on my 2005 Town and Country. I cycled the IOD fuse, which had been working as a temporary fix, and then I also disabled the 18 MPH auto lock feature using the owner's manual. It's been about 3 weeks now and the problem hasn't returned.

Thank author of this post/comment"What if it is only the driver door power lock?"

1) Would the IOD fuse pull temporarily fix it?

2) Would it be safe to say it is the actuator in the driver door?

Thank author of this post/comment"Intermittent Problem Stopped"

Have been dealing with the intermittent door lock issue for a few years, using the IOD fuse to reset when it happens. The cargo door on the passenger side recently stopped working totally (other than manually), and now the other locks works just fine.

I may need to change the actuator in that door, or just keep locking and unlocking it manually. That is a little inconvenient, but not as bad as the prior problem. At least now I know which lock was causing the problem.

Thank author of this post/comment"DOOR LOCK ACTUATOR"

Reference to ASH response about one of the door lock actuators being the underlying issue. This makes perfect sense to me why pulling the fuse will temporarily fix the issue. Apparently the BCM is programed to lock out the signal to the actuators if there is an issue with one of the actuators. The temporary fix works until the BCM again senses that one of the actuators is having problems.

My question to ASH is where was he able to obtain just the actuator motor in order to fix the problem for $2 vice $40....

Thank author of this post/comment"2008 dodge grand caravan"

A bit of a twist to the norm here but my door locks are functioning by themselves, can't get out of the van or into it. I am wondering if the components are subject to moisture and possible shorting something out. I pulled the fuse, manually unlocked all the doors and it seems to drive fine without faults at the moment.
