Buick Riviera 1995 electrical issues
 

Hi guys, I have some problems with my 1995 Riviera. REAR VIEW MIRRORS AND MEMORY MIRROR AND SEAT ADJUSTMENT NOT WORKING at all. Checking the owner's manual I can not see a fuse for the mirrors but I think it has to have some fuse for it, it has to be able to blow a fuse if it gets over loaded. The seat can be adjusted (motors are working fine), but I can not set the memory for the adjustment. I wonder if this issue is coming from the switch block (on the door panel), the BCM, or some fuse needs replacement. Can somebody give me a hint please? Thanks a lot.
