Question about 2004 Oldsmobile Silhouette
The fan switch will not work on position 3 and 4 does not work. Position 1 2 and 5 work just fine. Do you know if there is a way to determine what the problem is?
More then likely the switch itself is bad. Chances are the contacts inside the switch are not connecting and allowing the motor to operate in those positions. If possible, try a known good switch in it's place.

You have a problem with the blower motor resistor. This is a very commen problem on all gm cars and light trucks. The part is not to pricey. You can find the resistor under the glove box buy the blower motor. Two bolts and out it comes.
