I have an 03 SS that we bought new. At times the heater blower motor doesn't work, the upper message center is blank and the green cruise light is on. Once I hit a switch like the blower motor, built in garage door opener, moon roof etc. everything is back to norman.. Any ideas?

 

Could be the BCM(Body Controle Module). This thing controls almost all of the electronics inside the car. You have to have a new one programmed by a shop or dealer with a Tech II scanner.

I think mine is starting to mess up as I'm having some weird electrical things starting to happen.

My car seems to have a few electrical issues it's self, but I'd start with checking your grounds just to get it out of the way.
