Car: 2000 Pontiac G.A. 3.4
Just noticed the other day that the 2 lowest blower settings don't work. Noting comes out of the vents as though it's off. When I move the fan setting to "3" it suddenly comes out at the regular 3 speed, which is too high for most situations.
What could be wrong? Does the actual switch need to be replaced?
Thanks
