Loss of One or More HVAC Blower Motor Speeds on Oldsmobile Alero

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Same..the blower only works on high. Good heat, just can't reduce. My daughter is hard of hearing, and it makes it difficult when she can't turn it down to hear a conversation. Very annoying!

It started making a funny noise when running AC/Heat. Then finally the 3 lowest settings stopped working all together. Only the 2 highest settings remain working. If I could figure out where the switch is at, I would test it to fix the problem!
