1. Check internal circuit of controller for resistance as follows.
a. Measure resistance between "1" terminal and "2" terminal of blower motor controller.
Blower motor controller resistance
"1" - "2": approximately 10 kohms
If resistance does not meet above specification, replace blower motor controller.
b. Using ohmmeter, connect its positive terminal to "3" terminal of blower motor controller and negative terminal to "1" terminal of blower motor
controller and check that there is no continuity.
2. Check controller for operation as follows.
