LH door opens but radio and lights stay on with key out.

[tonyghkbve]

My 07 Silverado classic, WT 4.3, has this problem that happens quite often. The LH door when opens with key off, the radio and lights stay on, and when I open the right, it stops that. Furthermore, when opening the LH door, the interior light does not come on, whereas it is the opposite for RH door. I think I have this question before, but it was a very long time ago and I didn't have time to go through it to find a solution. If anyone here can help me, that would be greatly appreciated! Thank you for your time.

Door latch gives an input to the BCM for the RAP ,

 

You need a scanner and experience to verify this ,

 

Shop time I'm afraid

I have the same problem. Only thing is that it doesn't work for either of my doors. I'm going to Check the actual BCM at the dealer...

Well, since this is not an extremely degrading problem, i might wait until I get a reprogrammed BCM from a 2LT Silverado since i am going to be doing a 1LT upgrade by adding pw, pl, pm, short o.h console plus a rear window defog.
