The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.Google+

The 5th speed on the fan doesn't work. I tried replacing the resistor, fuse relay and switch. Still not fixed.
I have this problem too.. The fan works on every speed except 3. What exactly is the way to fix this?

#1 on ac switch went out first, then 2, 3, and 4 after that. After I changed the resistor, then the blower motor went out. Changed that as well. Now it's doing it again.
