93 Max Power Locks, Alarm, and other woes

I have a 93 Maxima. Everything electrical is going to crap. My power locks don't work. When I unlock the car with the key the alarm activates. My seat belt bell keeps going off and my antenna shuts down whenever it decides it doesn't want to play anymore. Additionally the driver side power window switch doesn't always do it's job.

Does anybody have a clue if these things come from a central source, or should I drive the thing off a cliff? :banghead:

have ya checked the fuses?

With that many problems, sounds like bad ground somewhere.

I have checked fuses and fusible links. There is nothing in the manuals that explain where the fuse or fuses for the door locks are. I am wondering if there is a relay responsible for them that I don't know about...
