Classic/Antique Car Repair: 1976 Corvette, gas gauge, gauge cluster

Question
Hello,

The 1976 Corvette heater will not work along with the gas gage, the radio, and the controls above the radio. Why is this? Do you think it can be fixed?  

Answer
Christy were going to have to do a few rounds on this one so be patient

First is it only the gas gauge in the cluster that does not work? how about the amp?, oil, temp...forget the clock..lol those never work. Are the lights working?

You stated controls above radio? you mean the gauge cluster?
or the wiper and washer above two duct vents

We'll get to the radio and heater later.

E-mail me back asap

thanks
Mike
