You probably have a bad resistor pack and/or a burnt mating connector for the resistor pack. It is located behind the glovebox, mounted to the blower motor. See picture below

Fan is not working on 2001 Chevy Silverado 2500 truck radiator fan motor?


The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block.
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the low fan fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan s/p relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the high speed fan relay and the cooling fan s/p relay through the high speed cooling fan relay control circuit. This energizes the cooling fan s/p relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the high speed fan relay coil is energized closing the relay contacts and provides battery positive voltage from the high fan fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
Your best bet would be to take your vehicle to a qualified repair shop !

2006 chevy silverado blower fan not working right. The control does not work. It still blows on low but nothing else. Cut key off and fan still blows.


With one speed working it is more than likely the blower motor resistor (20 dollar part) located in the area of the blower--needs air to pass by it as it gets rather hot), or at worst case the Module. This part (Blower control Module) is a bit more expensive. Try the resistor first, you can test its resistance at different speed settings to see if it is functioning as it should.

Heater motor only wokks on high


probley the restor that gives the a/c heater fan motor its power for the low/ medeam speds has gone bad and onley letes it run on high speed because it gives the fan motor full battery voltage on high speed. it should be located in the heater box were the fan will blow air across it to cool it when it is in use GEORGE STIRBER DBA AUTO ENGINEERING
