Electrical problem
 

I need a Chevy/GMC genius! I had multiple accessories fail all at the same time and need to know what the common thread might be. Started with the driver side electric seat, then the remote door entry fob would not work, then the anti theft alarm/horn went off as well as the lights started a blinking. Quick fix on the horn was to remove the #29 fuse. The interior door locker works, not the remote. I pulled the two breakers in the engine compartment and the three in the cab for an hour, reset them with no effect. I don't see any blown fuses. Does anyone see what would effect all of these items?
