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.

fan speed only works on high setting.
Lost speeds 1-3. 4 and 5 work fine.
Doesn't work at all.
The 5th speed on the fan doesn't work. I tried replacing the resistor, fuse relay and switch. Still not fixed.

heater works on high only
Fan speeds quit working one by one until only the highest fan setting is left working.... at least for now!
blower runs for a few minutes then it slows right down. when i start the blower i start it on full blast and get a couple minutes out of it before it slows to a stop.
Setting number 1 and 2 on the ac fan switch doesn't work.
fan speeds 1,2,3,dont work
Speeds 1-3 not working.
I am living with it, as it still works on 3 and 4
Heat would not work on 1 2 or 3 has worked on 4 and 5. Just recently it has stopped blowing out heat and nothing blows out anymore
No air blows from vents when switch turned 1-5. Replaced blower motor resistor and worked for 2 days level 1-4.
My cars air speeds have stopped working. it was working for the 4 and 5 settings, now it stopped.
The heat / air only works on the highest speed and it's not blowing out real hot air. I don't know about the air conditioner, too cold out to test it.
ac does not work due to blower motors not working. heat will not come on until it is on number 3 back window brackets broke so window does not go up or down
