Yukon a/c blower doesn't work on low settings

My 2000 Yukon A/C fan only works on the higher settings. Level 1 went out months ago, now level two isn't working. I get air pushed out at level 3. Is it the switch or motor?

I really think the Blower resistor is at fault.
It is located on the Passenger side, directly next to the blower motor.
It has a 7 or 8 wire connector from controller,  and then the 2 wires coming out for the motor.
They are VERY common problem.
2 small screws holding it in.
easy fix.
Part SHOULD cost in the $40-$50 range Depending on which Auto parts store you go to, Auto Zone will have this part and can give you the step by step instruction to get the job done. 
Hope this helps.
Good Luck

Blower motor doesn't pump well even the fan switch on high


sounds like blower bearings are dried out and will eventually lock up the blower..sometimes you can spray wd40 in the blower bearings and it will work fine for a while.. also check vacuum controls to the baffle dors in the ductwork..may have some leaks there.. should hear a slight hissing if really bad..repost findings

2000 Pontiac Grand AM little heat being produced.


1st thing to do is change the thermostat. It is either missing, or stuck open (you provide good info). This is why the car is not running at operating temp and why you have little heat. The no blower for settings 1-4 probably means a bad switch.

My 2000 GMC Yukon 2WD's heater fan now will only work on level 5. First level went awhile ago and every couple months since another one would go. Once level 5 is gone I aint got no heat no mo ! Help !


There is a resistor down below the blower fan on the inside firewall of the passenger side. Advance or Auto-zone carry them and they are not hard to replace or very expensive. You will have to have a small socket though. I am not sure it is a 6 or 8mm.

You will see a long plug about an inch and a half that goes into it. When they burn out you only get high as a default.

Hope this helps.

Fan works on Full Setting ONLY. 98 pathfinder


there is a ballast resistor that should be next to the blower motor that controls the low speeds on the blower. change it and you should be all set.
