When I purchased my vette the heater fan didn't work. I have fixed everything else and now wanting to fix the heater fan. Under hood on Passenger side I found a bundle of wires taped off

Green
Purple
blue
yellow
brown
black

Also found a wire with one half of fuse ( female) I see the heater resistor on top. The wires Y off with a red and black wire going under to somewhere. I believe the yellow, green, blue go to resister. Any help its a a/c car but no compressor yet. Thanks for your assistance.

"A picture is worth a thousand words" or so they say and in this case a picture would certainly help us solve your problem.

AND is your car equipped with FACTORY A/C????

Yes but not hooked up. The wire that has the fuse (1/2) is orange. And has 12v when key is on.

You are correct that the blue, green and yellow wires connect to the resistor.

And the other wires connect to the heater blower motor cut-out relay and A/C thermal limiter fuse.

See post #6 from Willcox Corvette for an excellent troubleshooting explanation.

Thanks that was helpful. I am missing the relay so need to get that.

This may help you too.. same for 1975. And if you need the connectors I should have them too.

Rogerl

Thanks that just what I needed

Rogerl

Do you have the connectors and how much are they and part number

0Willcox Corvette

Which connector do you need? I should have them.. just post back and I'll see if I can get you the proper link.

I need the connector for the relay and the resistor. Thanks

0Willcox Corvette

I should have.. I don't have them up on the site but I should have them. It will probably be Monday before I can look.

Did you find the connectors? For relay and resistor.
