Sup HT,
I need some help troubleshooting a problem that I'm having. During these winter months, my gone from blowing full blast, to blowing whenever it decides to, to not blowing at all. I've checked all my fuses & even replaced my fan. Still nothing. I need suggestions. If it helps, I replaced my compressor last summer...

 

Probably need blower motor fan switch. Resistors are known to fail.

 

Is it an easy fix?

 

So should I replace the switch or resistor?

 

Source a used switch from a bone yard or pay about $45 for a new one.

 

Agreed. If it only works on high speed go were other the resistor

 

The fan spins when it's on high speed but nothing blows out...
