Hello

First of all hello, ok, heres the deal Cadillac headlight chime is constant when I turn the headlights on, and doors are shut, this just started, plus fuel guage stopped all of the sudden, also, volt meter reads zeros, also a/c blower comes on automatically, and trip meter resests when car is off. All of this happen together, the chime the guages not working etc, besides that car works great, and no messages telling me something is wrong. Before all this I would have just airbag message, which was ok, because the airbags are blown. I have checked fuses front and back, all seem well, my mechanic checked the volts with his scanner and says they are fine on his scanner, but dont read on cluster in the car. All. Like I said started all together bam!The Dic codes I get are just airbag codes, but once again no more "service airbag message" its strange what could all this be. Thanks. Oh. Almost forgot heating and cooling temps on analog go lower or higher when car is off, like theres no memory.
