2003 Yukon

The fan in my yukon quit working, all fuses are good but fan is out. The rear fan works fine. When I removed the plastic cover to get to the fan I noticed the power goes through a box? Does anybody have any clues on were to start.

Sounds like a bad resistor and connector. The resistor is the module with the two wires going to the blower motor. It also has a connector that has about 8 wires. Unplug the 8 wire connector and see if it is burnt. If it is post back and I will give you the part numbers.
