I have a problem with my 1998 Blazer LT 4WD. The power window switches work but none of the power lock or mirror switches work. Also, the back hatch window buttons don't work, neither on the dash or on the keyless remote.
If I want/need to open anything other than the driver's door, I have to either reach over/back or use the remote, even when sitting in the vehicle.

This has lead to another problem. I have 1 programmed remote, and 1 that isn't programmed. I've found plenty of videos on how-to program the 2nd one, but since the lock switch doesn't work I can't go into programming mode
