1972 C3 blower motor help

[Tom L.]

Having a problem with my blower motor. The 3 lower speeds work fine but it doean't operate on high at all. It's an A/C car but it isn't installed at this time, not sure if it matters. Just wondering if there are any areas I should look at before I start digging into the wiring. Thanks!!

Check your high speed blower relay, located on the engine compartment side of the heater box. Check to see if it is getting power, if not, check in the inline fuse located on the left inner fender.

That would be the relay behind the resistor and kind of under the wiper door actuator right?

Just following up. Seems the fuse holder on the driver's side fender broke a while back. The barbs that lock the two sides broke off. I guess the previous owner didn't mind the fan not working on high. Replaced the fuse holder and all is good. Thanks Dick!!
