My heater & A/C control (fan) switch has 1 to 5 settings, but the fan only operates on 3, 4 and 5.
The car is a 2000 Pontiac Grand Am SE.
I would like to know if it is the fan motor, a resistor of some sort or possibly the switch? Also would like information as to where the problem lies and the procedure to fix it.

I viewed your Web Sites "2005 Chevrolet Silverado Blower Inop" and thought that was an excellent repair procedure.
Your assistance will be appreciated.

Hi Nelson,
More than likely the blower resistor is the problem. It is located under the right side of the dash behind the glove box area. In order to test you will need to remove the lower hush panel and the blower resistor should be located next to the blower motor. Disconnect the harness connector and check for voltage at the yellow wire with the switch in position 1 and check for power on the tan wire with the switch in position 2. If powers are present the resistor is faulty. If powers are not present then there is a problem at the switch. Due to the fact that you stated that positions 3,4,& 5 work, this confirms that the blower and the blower relay are working. If you happen to find signs of water please make sure that you clean the a/c drain tube or the problem will return.
