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
only the two highest speeds work
Fan blower doesn't work at all 2004 old's alero no heat or air
only top two blower settings work
1 fan speed high worked now fan speed altogether quit
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.
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.
Lower speeds on blower do not work
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 two high blower speeds work.
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 works on highest setting or doesn't work at all and makes a really loud noise.
no heat blows out at all there was but stopped completely
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.
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!
Blower motor started making a loud noise & then just quit working all together for AC
Only the two highest speeds work.
When I'm driving I can feel the heat or cool but it doesn't blow out and when I stop I can't feel it at all.it use to work just on high but completely stop.
Since 2011 the lower two speeds of blower switch do not work. Have not fixed it.
