Climate Control Problems

If you have the manual climate control, the blower motor wire colors are green (with a red stripe) and black. For the electronic climate control the colors are yellow (with a violet stripe) and blue.

Yes, the voltage will change with the fan speed setting. However, with the connector removed (or an open motor), and a manual system, full voltage (12V) will be at the green/red wire for all settings (black is ground). The electronic system turns the motor on at off at a fast rate (about 100 times a second) to control the speed, so voltage will depend on what speed is being set by the control unit.

If you have the manual system, try the blower switch at the highest setting. This position bypasses the resistor module. If only the High setting works, the problem is not the motor.

Also, be sure to check the fuse (#31, 25A).
