Chrysler Repair: Trunk Opens & Doors Lock/Unlock by Themselves, 1994 chrysler lhs, chrysler lhs

Question
QUESTION: On my 1994 Chrysler LHS (50k miles), the doors will lock or unlock by themselves and/or the trunk release will activate on its own. The car only has the OEM remote entry system, and the remotes are not touched, nor are they anywhere near the car when this happens.

I've only noticed this occurring when the car is parked and the engine off. I'll leave the car for sometimes only a few minutes, and when I come back, the trunk will be popped open or the locks will be unlocked (or they'll be locked if I left them unlocked). This also happens every night when the car is in the garage.

Is there a way to fix this?

ANSWER: The '94 manual only discusses the failure of the door locks/decklid to open when requested, not the reverse problem. I would suspect this is a problem with the remote keyless entry module itself and maybe the easiest/least expensive approach would be to find a replacment module at a wrecking yard. I can tell you how to install it and reprogram it to your remote. The unit is accessed by removing the top cover of the instrument panel and you will find it on the right side structural duct.

QUESTION: When you say that the remote keyless entry module is on the right side structural duct, is that located behind the glove box?  Also, is there a way to test the module?
Thanks!

Answer
Hi Mike,
No the module is between the top pad and a large air/demister duct that runs across the dash just below the top cover. You gently pry up each end of the cover, then pry up the rear edge all across the dash, then lift the rear and pull the pad rearward. Install is the reverse but be sure to engage two center clips to start, then press the rear and the finally the ends into their clips. You might want to also use your thumb through the vin opening to move the vin so as it is visible when the pad is back in place. I don't think you will get to it via the glove box.
I don't know of any way to test it. If you pull the 2-wire blue plug that will take its power away and then you can see by default if the problem you have is gone. That is one approach to 'test' it, because it is one of several circuits that operate the several troublesome locks, and if the locks then act normally it would thus imply that the remote itself is the issue.
