Waiting for a blower motor resistor to get here Thursday, speed one is out, speed 2 is out, 3rd. and 4th. speed work. But high is out too. I am pretty sure the resistor will fix the lower speeds, but I understand high speed bypasses the resistor.
Fuse HVAC HI has poser both sides. Fuse DIC/HVAC has power both sides.
Fuse HVAC control has power both sides.
I have seen reference several times, to a blower motor relay, contained in the blower motor resistor.
Could the relay built into the blower motor resistor control the high blower speed and be bad also?
According to a few wiring diagrams I have seen, they do show the high speed blower motor voltage going through a resistor.
Has anyone seen the blower motor resistor replacement also solve the issue of no high speed blower motor operation?
Thanks guys.
