Just bought a 99 Grand Prix (non super turbo - whatever).

Needs some work. It runs ok and is smogged. That’s half the battle here in Calif.

Some issues:

Heater core was bypassed - I assume that mean a replacement

Front windows do not work. - Is that a fuse? window regulator? Motor? How can i test? Is there any technical data regarding voltage readings I can test for at the switch to see if there is a short or help isolate the issue?

Power mirrors do not work - Switch? Fuse?

Fuel gauge is erratic - Sending unit at tank? Does that mean dropping the tank and replacing? Or is there something behind the dash I could check?

That’s' it for now. Any help or direction would be really appreciated.

I did buy a Chilton’s but as usual the information there is vague at best.

Thanks gang!
