Where can I get a replacement for my high speed fan relay for the AC & Heater? I am currently getting the AC working in a 73 small block, and the one thing I can't locate is the replacement relay. This is the one that is on the firewall, or actually it kind of mounts to the AC box near the innner fender.

A local Chevy dealer has no idea on it, and I can't locate it any of the catalogs. Does anyone know where you can pick this up at?

Thanks,
Rob

I just found in the zip catalog, the part OE part # 1115881 for the Blower Motor Relay. I am thinking this may be it?

If you are getting all the fan speeds except high, I think it may be the inline fuse for the AC. It was a large orange wire on my 71 which goes from inside the car to the horn relay. Not sure if its the same color in your 73.

I'll check on that too. Thanks.

The ONLY differance between a CORVETTE h/speed blower relay and one off other cars of the era is an extra connection for the ground side of the coil, which runs through the harness to the engine...part of that black wire allways confused on the starter.....
now the thing is, the plugs will more or less fit the say '70 GTO fan relay...but, that gound has to be put to the relay FRAME.....and not a plug tab....
