Common module to locks, trunk, horn??
Is there a particular module/relay that is common to the horn, keyless entry, trunk release and perhaps windows? Reason I ask is that none of these items work with the exception of the passenger window which works fine sometimes then quits then works then quits for no apparent reason...........all fuses are checked and good. Any ideas??

Sorry...........its a 00 SLE.....

What year is your car?

i had almost the same identical problem you may need eith the rear integration module or the BCM neither is cheap and they must be programmed by the dealer.

to know for sure what you need no code scanner other than a TECH 2 can read those codes. going to a dealer and paying the hour for the testing would be your best bet for mine it was $90 depending on where you are located. if you are around NH i could get it done for ya a lil cheaper and may have the parts locally available (used and much cheaper).

Dam.......not what I wanted to hear, was kinda hoping I could handle this myself.........are there no tests I can do to confirm either way? And where are these units located physically on the car?

the rear inegration module is in the trunk behind the vertical plastic. the BCM is under the dash on the passenger side

Hmmm...........wonder if that unit is getting wet due to my blocked AC drain?

very possible. one test that may help you out would be ground bus corrosion this is for a different year but will give you an idea
