Driver Window/Door Issue
Hello all, the other day my alarm went off randomly, just once, chalked it up hitting the fob in my pocket or something. Went to lunch later and noticed the RAP wasn't functioning and window not indexing...hmmm. Next day did a lot of driving, the whole time the DIC was telling my "drivers door ajar" so I ordered a latch, well because GM has had issues with the micro switches in the past. Fast forward to today, I swapped latch out, still no RAP, hooked scanner up, no codes, function tested ok, but noticed the lock indicator light kept flashing, low and behold the scanner showed it cycling on/off, lock the door, light goes solid, no bouncing, but doesn't go out after a few seconds, and interior lights stay on. I'm leaning towards the DDM, but not sure how to check it before dropping almost $500 on new one. Every switch checks out, window goes up and down(not all the way up), mirrors adjust, memory seats recall, door opens from inside and out, power top functions like normal, doors lock and unlock.
