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.

only the two highest speeds work

Blower doesn't work at all
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.

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
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 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.

Fan blower doesn't work at all 2004 old's alero no heat or air

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.
2001 Oldsmobile Alero123,000
no heat blows out at all there was but stopped completely
Since 2011 the lower two speeds of blower switch do not work. Have not fixed it.
Three lower speeds failed just before winter. Resistor replacement required. Doing it myself so waiting for Spring
Blower only works on the highest speed. Also when the temp is turned to warm it stays warm even when the temp is turned to cool.

First two settings have never work and I have had my car for over 11 years. I just figured the settings were for other models of oldsmobiles.

The only settings that works are 1 and 5. The blower motor resistor goes bad a lot.
Only the two highest fan speeds work.
Lost speeds from slowest up, then stopped responding altogether. Replaced the resistor pack. Worked for a while, then stopped on all speeds almost simultaneously. Replaced resistor pack - no fix. Replaced blower motor - good. Then, about 2 weeks later, it all stopped again. I just gave up. Worst problem is no defrost, but I can live with heat and cold.
