Hello, did you check any fuses? Can you get at the blower motor to do some testing?

It doesn't blow on any speed?

Did you check that the fuse circuit was hot, even if the fuse is good, if the circuit isn't hot, it won't matter. Check the high blower fuse 30 amp. That voltage circuit goes through the resistor assembly, it's a relay type circuit, but it doesn't go through a resistor.

You might take the blower connector loose, use jumpers off the battery posts for B+ and ground, see if the blower will run, use an inline 30 amp fuse. I'm not sure of the wiring colors, black is usually ground.
