sup folks ac just started acting funny its only working on the 4th setting.

blower motor resistor

I think I'll go kill myself now.

Maybe we can start deleting threads that are basically duplicates of others.

 

only if it's manual climate control is it the blower motor resistor.

If it's auto, then it's the fan amplifier motor or somethin

 

Do the autos even have this problem?

 

The manual controls that use the resistor will have the problem where only the high speed works. The auto climate controls that use the fan control amplifier will either have no fan at all or the fan will run at high speed all the time and you can't turn it off.
