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

Problem Description and Possible Solution

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.

Blower doesn't work at all
Fan blower doesn't work at all 2004 old's alero no heat or air
only the two highest speeds work
1 fan speed high worked now fan speed altogether quit
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!
only top two blower settings work
blower stopped working and intermittenly works at a very low speed. Resistor pack was not the problem. We are still trying to figure out what is wrong.
Lower speeds on blower do not work
only works on high, if you leave it on anything but off or high you can hear a weird noise every couple seconds like something is trying to work. not fixed yet.
The first two speeds quit working on the blower so I only have the upper speeds, which sometimes are to high for my newborn.
heater/air condition fan no longer functioning
Only two high blower speeds work.
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!
Only works on highest setting or doesn't work at all and makes a really loud noise.
blower motor only works on top two speeds
The first two speeds of the AC are not functioning. It's either a full blast or air in my face or nothing at all.
no heat blows out at all there was but stopped completely
Blower doesn't work at all
First one speed of blower moter went out than a second now no heat at all.
i will turn ac on and the blower will kick off for a while or until i shut the car off and start it again. this just started yesterday.
