C2 67 Blower motor/AC relay question

[Terry S.]

I was just trying out the factory A/C and the highest setting on the blower stopped working. It still works on low and medium. Any ideas on what to check? With the harness plugged in to the blower motor resistor and turning the control knob from medium to high I hear the A/C relay click loudly but it doesn't click when I turn the control knob from off to low to medium.

I took out the A/C blower motor resistor and the one coil is a little dark, the other coil looks fine. Is there a way to check that resistor? I tested the harness plug that goes into the resistor and get continuity with the yellow to purple wires on low and the light blue to purple wires on medium, I get nothing when the setting is on high. Any ideas?

Thanks

The A/C high blower speed at the relay is fed by a separate red wire that's connected to the screw-terminal buss on the horn relay, and it has an in-line fuseholder containing a 30-amp fuse. I'd check that fuse first.
