Why is my ceiling fan not changing speeds?
The bad capacitor can cause speed problems. You should always inspect the capacitor whenever you experience any speed problem in your ceiling fan. As the capacitor cannot be fixed, you should try this after checking the lubrication and blades. When none of these prove effective, you can replace the capacitor.
Why does my blower motor only work on high speed?
Many, many times a car or truck will come into the shop with the customer complaining that their blower motor doesn’t work, or only works on high speed, etc. This is usually the case after a blower resistor failure on one or more speed settings.
Why does my heater not work on high speed?
Heater blower motor will not work on high speed? I have replaced the black bosch relay behind the glovebox, the blower resistor and the blower motor and still cannot get the blower to work on high. I remember in older model years of gmc’s and chevys that their was a high speed blower relay that caused this issue.
Why is the resistor not working on my blower?
Hi There, The resistor is what controls the speed of the blower motor, not the relay. The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all.
Why does my GMC heater blower not work?
I have replaced the black bosch relay behind the glovebox, the blower resistor and the blower motor and still cannot get the blower to work on high. I remember in older model years of gmc’s and chevys that their was a high speed blower relay that caused this issue. If there is a high speed relay, I can’t find it. Any suggestions?

Why is my blower not working in Hi ( 5 )?
The usual failure of the resistor pack is if it works in HI (5) but not in any other mode or just a few modes. When you switch to high,the blower motor relay coil circuit is grounded and voltage is now applied directly through the relay to the blower motor; bypassing the resistors. So, I would look to see if the relay is ok.

How do you change the blower motor on a car?
Removal of the right side dash trim is usually all it takes to access the heater/blower area of the vehicle. A couple screws later and the resistor is out and unplugged from the blower motor. Installation of the new resistor is just as easy, and has a new harness that plugs into the existing blower motor. Now it gets just a tad more intricate.
