My guess is it is a trim option, my unit doesn't have keyless entry, or the overhead maplights/compass but it does have power windows and door locks and my driver side door jam switch is wired. Anyway this thing is working fine but for how long I don't know, thanks for the help guys.

 

is this located in the same spot on the 96?

 

I open the drivers side door, and the interior lights don't come on??

 

Ok... Did you read through this thread? What testing have you done?

 

inherited a heater core job on 96 2-dr blazer It was disassembled but left for dead.
After making best guesses on hookups and where the big bag of assorted screws and bolts went, It looks right, but the dash lights are on and the warning buzzer (like you get when turning off key with lights on). Even with both light switches disconnected. There are two connectors (a red and a green) with no apparent plugs. I assume they are for optional equipment. Any ideas?
