I have an 87 Camaro which was originally an LG4 with A/C. I built a 383 for it, removing the Computer Controls of course. Also removed the A/C, except for the blob on the firewall. Just went through the Trouble (note the capital 'T') of replacing the heater core and figure that I might as well have everything working. Since the motor swap the heater fan Hi-Speed has never worked and I didn't care to much as this is a fair weather car. Now I would like to get it functional.

Any guidance would be appreciated.

Thanks Md,

Back when I did the swap I grounded the the fan directly to the chassis because the wires looked like they had been fried, the relay looked cooked as well. That was okay for Low and Med but not Hi. I left the old burnt ground wire hanging there. Today, after checking all the wires for Volts etc. I grabbed that old burnt ground and held it against the chassis and VIOLA!

Thanks for your response.
