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 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!

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.

The first two speeds quit working on the blower so I only have the upper speeds, which sometimes are to high for my newborn.

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.
the blower motor speeds go from all speeds, to not at all or lowest possible speed, continuously all the time all day long ranging in one to three minute intervals. Mostly on the lowest speed which is very irritating but also makes it very so to warm in the car especially on these frickin cold wisconsin days. Very much a pain not to mentien may be dangerous and could cause wiring default and fire its a hazzard and also deserves a recall!! Its not fixed why the hell should i have to pay for a default in any kind of engineering design!!!
As described by others
The blower fan just had a low speed and a very high speed. Dealer had to replace a part. Cost about $200ish dollars.
My AC and heat only blow out on the highest setting, but nothing really comes out
