2005 chevy trailblazer interior lights don't work help me troubleshoot the issue

Most times it is the light switch when none of the lights work. Can you manually turn them on? This over rides the BCM. Interior lights are controlled by the BCM. Try opening the passenger side door, see if they come on. If so, replace the drivers door latch, inside the door. If still no lights. The BCM needs scanned for codes.

Where is the BCM located on a 2002 Chevy Trailblazer

the remote entry lock module, ensure the Body Control Module (BCM) is correct for your 2002 CHEVROLET TRAILBLAZER with a 4.2L engine. Special restrictions like "California only" or "with sport package" may indicate a Body Control Module (BCM) fits only certain 2002 CHEVROLET TRAILBLAZER models.
the bcm has to be programmed by a dealer,go to your dealer to make sure that is the problem,it could also be the ignition switch,it usually mimics a bad bcm,a switch is cheaper.

    Right front door control not working for window, lock and mirror

    All 3 are controlled by a Passenger door control module located inside the R/F door. It is a computer and communicates with other computers on a data line. The main one in relation is the BCM ( body control computer ), It could be an issue on the data line where they can't communicate with each other. The PDCM could be at fault also, check the fuses, if the module doesn't have power it won't work all 3 functions. Best to get it scanned at a garage or a large auto parts retailer, usually for free. It could be a trouble code for the PDCM or a loss of communication issue. Either way you'll have to have it repaired at a garage if either problem. A new PDCM or BCM will need to be programmed afterwards.
