I just picked up my 76, but can't locate the fuse box. So is there anyone out there that can help? Also has no air or heater. Where can I get a schematic of where eveything is.

 

Welcome to CF. Your fuse box is under the dash on the firewall on the left side. You have to lay on the floor and look up under there to see it and replace fuses. It is a tight fit in these cars. The best references you can have are the Factory Assembly Instruction Manual (AIM) and the Vehicle Service Manual. There are very detailed drawings and pictures in each manual that will assist you with most of the parts and operations of your car. If you are having difficulties figuring something out, you can always ask here. I am sure someone that has done it before will chime in.

 

Welcome to CF!
You can get those manuals from Ecklers, and they have them for your year of Vette.
