The power door locks on our 2005 Caravan SXT are giving me problems. After driving one day, all of a sudden the driver's door lock button would not work, but the passenger button would. Next day, neither would work. The keychain remote will arm/disarm, but will not activate locks either. However, the lock buttons will lock/unlock liftgate only. Body control module was replaced 1 yr ago. Could this cause the problem?

I have had the exact same problem you are describing. We bought this van 5 months ago and have been dealing with all kinds of issues ever since. This was a Dodge Certified Pre Owned with only 22,000 miles on it. Our 1997 Grand Caravan was more reliable than this van has been. We have had the body control module flashed2 times. Then 3 weeks ago they replaced the body control module. Last night the locks died again. Both door switches are dead and the remote locks don't work either. We also had to have the sway bar bushings replaced @ 25,000 miles because of the clunk in the front end. The A/C has a leak somewhere that they can't seem to find because it was low enough on freon that the compressor wouldn't kick on, And it has had the recall done. The right rear door had a terible rattle in it and they finally fixed that after 3 trips back to the dealer. We had a leak in with the sunroof which they did fix. All of this in just 5 months. Yes its under warranty but I can't tell you how many hours we have wasted taking this to the dealer which is 30 miles away. We like the features of the van but the reliability is crap, no wonder Dodge is having problems selling cars. If someone knows of a fix for the power locks please let us know.
Talked with the dealer again about the power lock problem he said it is a static electricity problem, but they don't have a fix for it yet. The last time ours quit they had us unhook the battery for 15min. and that did reset the locks and they are working again. I will let you know if I findout anything else from the dealer.
Hey Folks: I have researched this issue since buying my 2005 Caravan in 2006. Here's the fix that I have found that works. Disconnect the negative battery cable from the negative battery post for more than one hour. This has permanently reset the computer in my 2005 minivan! Previous blog/forum recommendations spoke of 20-30 minutes; yet, the fix was only temporary. More than an hour seems to refresh the computer permanently and the problem still remains fixed now x about 3 months. Ed L.
Flashing the BCM for door lock problems is a well-known and documented solution for a well-known and documented problem on the '05 Caravans and Grands. It's not free, but it's only about $120 +/- and it resolved the problem on my '05 Caravan SXT. My remote works and the inside lock switch works. I had it done several months ago.
eksharp8, sounds like your dealer doesn't know much. I went in to mine and started describing the problem in great detail. After about 10 seconds, the writer told me about the problem and the solution, we wrote the car up and had it back before the day was done.
Tell your Dealer if they would type the words DOOR LOCKS into the search box on Techconnect they will find it. Every Chrysler employee and every CHrysler dealer on Earth has access to it. Sometimes I read these dealer stories and just bang my head on the keyboard in disbelief...lolzzz
Disconnecting the battery will maybe work for a few days but eventually it will start happening again. That flash just isn't for the door locks. There are all kinds of cool things it addresses....like the rear wipers just going dead too.
The right rear door won't unlock on my 05 Grand Caravan SXT when i use the remote or try to unlock it at the drivers side switch. I am going to start by checking the wiring harness to see if I get voltage to the plug when I activate the switch. Am i wasting my time, any suggestions.
How do I remove the door panel to get to the wiring and relay?
Back in November of 2011, as noted in my post above, I had the BCM flashed. I still have that beautiful Caravan and the doors, remote, and everything else still works just fine. The driver's side door lock actuator is getting weak, but that's a completely different problem for another day. Just do the BCM flash, it's a cheap AND CERTAIN fix.
