Ok there is a blower motor module connected to the blower motor. Looks like it has a 9 connector harness to it. Three look to be black, two go to the motor itselft and one goes to ground. Two orange wires one comes from the heater control should have power on speed 5 and the other should have power coming from the blower motor fuse 25amp. There is yellow speed 1, there is tan speed 2, there is lt blue speed 3, purple speed 4. Check for power to the module at the wires listed above when set on the setting listed for each wire. The voltage should increase as the speed increases. Let me know what you find ok.
