The blower fan on my 2003 suburban only works on high speed. I suspect the blower motor resistor to be the problem. Where is it located and is it easily replaced?
Thanks,
John

Most of the time it's mounted on the a/c heater plenum, next to the blower, yes fairly simple, unplug connector remove screws, pry out, snap new one in and plug in...

I agree with MERLIN2021, here is the location of the blower motor speed resistor which is right next to the blower motor so you can change it out and fix the problem. Check out the images (below). Let us know if you need anything else.
