Chevy Colorado Blower motor does not work

A customer came in with a Chevy Colorado and the blower motor does not work. Now, electrical problems can be really tricky, so I put our best tech on this one.

VEHICLE: 2008 Chevrolet Colorado LT 3.7L, L5, MFI, DOHC, VIN E, Eng Desg -

Customer Concern: Blower motor is inoperative. There is power to the motor.


1. At the blower motor, ground the Orange wire and see if the blower motor will come on.

2. If the blower motor works, check ground G106 located right side inner fender behind air cleaner.

3. If the ground is good, check for poor connections at the blower control switch on the climate control panel.

Blower Switch Circuit

Ground G106
