Coming home from a recent trip, the HVAC blower motor started screeching. It's always had a ticking when set to low, no bother, I just didn't run it on low. So I replaced the blower motor. I have both a Haynes and a Chilton Repair manual that I used to get me pointed in the general direction...

The heater blower motor sometimes starts up by itself but if it's not blowing and I give it a whack with my fist under the glove compartment it seems to start up just fine. I don't know if it's the motor or a switch or a resistor if someone could point me in the direction of what I need to...

1997 GMC Jimmy 4.3l engine. Ac/heat would blow intermit at differ speeds. Then just totally stopped. Checked 20amp fuse. No issue. Write ups said most likely resistor or motor. Replaced both. No change. Any suggestions? Relays? In-line fuses? Interior switch? Thanks for any tips
