interior lights

[blackjack]

pete,
thanks for your time (and patience)
what i meant is the door switch works fine...it only happens when i unlock the doors...if the doors are not locked,they work perfect...i understand there is a delay so you can get into the car,insert your key,etc...i dont think it can be adjusted...dont your interior lights come on,when you unlock your car,
even before you open the door?

According to the service manual, you only have 3 possibilities. The CCM, the courtesy lamp relay or a short in the wire from the CCM to the relay. The first thing to do is remove the courtesy lamp relay to make sure the lights go out or do not come on with the relay removed. If those results are as expected, measure the voltage at terminal 2 of the courtesy relay (grey/blk wire), the reading should not be at ground (0 volts) level when the lights should be off. It should be at 0 volts only when the lights should be on. My assumption is that this voltage will be close to 0 volts for the duration of time the interior lights are on. If that is the case your problem is with the wire from the CCM to the courtesy relay (unlikely) or the CCM needs replacing. The problem COULD still be something with the door ajar switches or the wiring to the CCM from them because the interior lights will "time out" after about 15 minutes and shut themselves off even if you leave the door open to prevent the battery from going dead. The door ajar inputs to the CCM are wires D16 (RH door) blk/wht wire and C12 (LH door) blk/yel wire on connector C1 of CCM, this is the grey connector. If you remove these wires and the problem does not go away, I would be fairly certain it is the CCM. The courtesy lamp relay is located in the bottom RH side of the istrument panel and the CCM is located behind the middle of the instrument panel. I hope this helps.

P.S. to my last post. I just checked and if the switch in the door lock sticks the interior lights stay on indefinitely (longer than the 15 second they are supposed to). The RH and LH door key switches tie together and go to the CCM at connector C! (grey) wire D15 which is a light green wire. I suggest either using a meter to make sure this wire is not at ground (0 Volts) after the key has been removed from the door or inducing the problem and remove this wire (without unhooking anything else) to determine if the lights will time out after 15 seconds. Good luck.

hi,guys
i wanted to write a follow-up on that problem i had...we finally discovered it was the switch tied to the door lock,the one that activate the interior light delay , that wasnt working properly...we changed the other door switch again,just to be safe,and now everything works !!! thanks to everybody,for your suggestions and precious help
