Default Re: HVAC Blower motor not functioning HELP!!

I pulled the 40 amp fuse and yes it was the wire. I tested the fan selector switch as to how it went to ground. The resistant went to close to zero when on high and increased as it went to lower speeds and then became open when off. So I knew the switch and resistor were both working.

So I had an open between the 40amp fuse and the fan motor. I then cut the orange/red wire just inside the firewall and ran a 10 AWG wire over to the fan. Then splicing it into orange wire just prior to the fan plug. Hooked it all up, replaced the 40 amp fuse and it worked great...........

Thanks again for the schematic. Without that I would not have been able to fix it.
