: Rear AC Blower

On my '94 Burb, the rear blower just stopped working.
I searched through many posts with no luck finding my symptoms.
The blower works when wired direct to a battery.
I have no speeds from the switches.
The fuse is good and I have power at the switch above the rv mirror and at the back on the large red wire.
I have 11volts going to all of the relays, but not when the front one is plugged in. Could this be a bad resistor even if I don't have a high speed?
Any help would be greatly appreciated.

I'm no expert but I'm thinking it might be a bad resistor because Ive heard many time of owner replacing them i hear they are prone to failure with age and use and the blower going out makes it sound about right with the resistor.
