Default '79 Electrical question

On my 79 I just recently got. The wiper switch, the tach, the oil pressure gauge, heater blower all don't work. Any chance thsese are hooked together somewhere ?
I checked all the fuses. The ones that are there seem to be OK. But there
are also some empty spaces and its too worn to read. Any help appreciated.

You've most likely got a problem with the ground wire under your dash. I never did find mine when I had these problems, but, the shop that fixed my A/C fixed the ground problem and got them going for me.

I don't know if this will help or not, but on my 79 there is a ground for the blower motor. It is on the fender next to the heater core. Another tip, if you do not have air conditioning, I unplug the ground and power wires during the summer so it doesn't burn me out of the cabin. That might fix the blower, but I'm not sure about the other problems. I hope this helps. :cheers:

The wipers and heater blower are definately on the same ground wire. Out under the hood.

Standard procedure with any electrical problem with a Corvette. CHECK THE GROUND.

Is there several grounds or just a couple main ones ? Thanks for all the input
Guess I better get a wiring diagram of the car. Hoping the problem isnt under
the dash.
