Chrysler Repair: electrical problem- interior lights


Question
QUESTION: '95 Chrysler Concorde, 3.3L V-6 engine.
Open door to enter car, interior lights go on (as they should).

Close door. The lights stay on (not good).

Place key in ignition switch and turn to run or start position - the lights go out.

Turn key to 'off'. Most times the lights stay off, but sometimes they turn back on if I hadn't started the engine.

My wiring diagrams cover almost everything except 'interior lights' so this problem has me baffled. Any help would be greatly
appreciated.

ANSWER: Hi George,
I believe that problem is a too loose interface between the door and the switch in the door frame which senses when the door is open or closed... it is just not reliably being 'opened' when the door is shut. The cause is because the door latch is out of adjustment, i.e. the door is not being secured against the door frame tightly enough. So notice that in the door frame there is a vertical 'striker' that mates to the latch and once you find that imply loosen its attaching bolts and move that striker in-board a couple of millimeters and then retighten the bolts. Then when you shut the door it will reliably push the switch far in enough as to definitely open the switch's connection that otherwise causes the interior lights to go 'on'.
Please read the PS (below) and respond to it.
Thanks,
Roland

QUESTION: Hi Roland,
I lost communication with you on this question.
Your most recent answer and my follow-up was
as follows:

Answer:    Hi Ron,
It sounds like you have the remote keyless entry (key fob) system, correct?          
That illuminated entry system uses a entry module to sense the signal from the fob and the body control module operates the system. The manual says it works like this:   
The IES turns ON the courtesy lamps (except the ignition switch lamp) when the  remote key is activated. The RKE entry module and bcm are to control the system. Courtesy lamps will turn on for 30 seconds and fade to off over a 5 second period.
When door is opened the IES will turn on the courtesy lamps and the ignition switch lamp. The lamps remain on while the door is open, then fade to off after 30 seconds after last door is closed.
Courtesy and ignition lamps will turn off as soon as soon as ignition key it turned to RUN.
After the ignition is turned off the IES cannot be activated for 30 seconds afterward. After a door is opened  and closed during the 30 second period, then system functions as described above.
If the battery voltage is interrupted to the IES, the system will not function until the fob UNLOCK is actuated.

My follow-up response was:

Hi Roland,
I bought this car used several years ago, so it never occurred to me that it might have a keyless remote system installed.

So to find out whether it did or not I did some inquiries on the internet.
I found this one website called http://www.keylessride.com, and typed in the VIN# of my car(a'95 Chrysler Concorde)and they directed me to this page:
http://www.keylessride.com/order/verify_keyless.asp?rke=optional&frid=B9E93AF5&m

I followed the instructions there and verified that yes, indeed my car has,supposedly, got this system - factory installed.

So, now that I know this, it gives rise to some interesting questions.

1. If I had a remote key fob, which I don't, would it help in diagnosing this problem?
2. Since I've never used the RKE system and don't really need it, is there any simple way to disable it?
3. If it was disabled, would it simplify matters or just make everything more complicated?
4. Which manual are you refering to. Perhaps I could obtain one also?

Just so you know-I greatly appreciate your knowledge and help. Every time I post I always give you the top expert rating

Answer
Hi Ron,
My last observation was that your interior lighting is working the way it is supposed based upon the description of it in my '94 Chrysler service manual.
But I would believe that if the lights stay on beyond 30 seconds after closing the door or leaving the vehicle, then it may indeed be because the driver's door is not being closed tightly enough which can be corrected by moving the striker in the frame in-board a bit. I would try that now. Also check for the same possibility on the other three doors by pushing outward on each door from inside the cabin to notice whether that causes the courtesy lights to come 'on'.
My next manual is a '98 so I am not certain that my conclusion applies to your '96.
I suspect that the RKE module being present is Not an issue, so disabling it will not change things; it appears to get involved only when the Fob has been utilized to enter or lock up.
So if you now can lock and unlock the vehicle by door key. though knowing about the presence of the RKE system, my suggestion would be to ignore it.
To get a Fob and program the system may likely require the intervention of a high level diagnostic readout box by a shop or dealer. It is that way according to the '98 manual, but not so from the '94 manual. You would tell by purchasing the '96 Chrysler service manual for the Concorde (LH body) most likely from eBay would be a good source. Look for listing "Chrysler service manual".
Thanks for you rating/nominations. You can do it again if you so-choose.
