Ok, it's starting to get hot already here in Houston. Time to get the AC on the 69 up to snuff. She's blowing cold, but the fan won't blow on high speed. I've checked the resistor package on the AC cowl - it is in good shape. I need help...it's getting damn hot on these black vinal seats!!!

I had the same problem with my previous '69 rs/ss convertible. I took the car to our local shop that works on electrical problems and they found either a part or a wire attached to a part defective. I don't remember what it was called but it had a cap on it about the same size as a horn relay cap and it was located near the top on the passengerside near the firewall where the ac is located. They either replaced the small part or found a break in one of the wires going to it. Whichever it was it fixed the problem and the high speed fan worked. I hope this helps some.

the part is the resistor, you need to make sure you get power from all the tap's on it. the filament can go but look fine.

take volt/ohm meter to it. on high you will have 12 volt's, you will get less voltage at the low and med fan speed seting's. if you have no voltage or i belive less then around 2 or 3 volt's. replace the resistor.

make sure the wire's are good too. you can have a internal break in the wire. or a bad conection at the resistor or fan switch. you need to get 12volt's at all position on the fan switch except off.
