Heater blower motor does not work on 2000 Durango: No codes

Question:

My heater blower motor suddenly quit when it was turned on. However, if a direct battery power and ground are fed to it, the high speed works. There is no code when scanned but I cannot find the relay connected to it. Suggestion?

ATS Advisor:

When you jumped the power and ground supplies and the heater motor works, it means the blower motor is OK. The motor is controlled by a resistor to vary the speed. It is usually located below the blower housing and that is a common cause of failure.

TIP:

Before you replace the resistor, make sure the ground wires are secure and not corroded. Contact ATS if you need assistance.
