Question about 2005 Chevrolet Silverado 2500HD 2WD
No fan function. Voltage tested with Fluke meter with key on and fuses checked. Regardless of switch position (5 position), "No voltage" getting to any lead at connector at fan module. At Fan switch, only (Black) has 12V. No other lead hot regardless of switch position. Bad switch?
the 30 amp breaker is behind the fuses ....u have to take the glovecompartment out and pull the whole fusebox out if ur hands r too big ....the power seat circuit breaker is there 2

There is a voltage regulator somewhere in that circuit. it controls the speed of the motor by changing the voltage in the circuit. Trace the wire back from the motor and you will find it, it's between the switch and the motor. They sometimes get hot and stop working on certain speeds. Change it out with a new one and check the amperage on the circuit to make sure you won't cook your new one. Good luck.
