I have a 2001 Chevey Suburban 1500 V8. The fan knob does not work on settings 1, 2, or 3, but does on 4, 5, and 6. A/C works fine, blower works on the upper settings. Any thoughts on a fix?


there is a BLOWER MOTOR RESISTOR located down towards the floor board on the passenger side under the kick panel... that resistor will... well.... lose resistance and only work on certain settings

My blower motor only works on 1 & 2 & 3 speeds dont work on 4 & 5. I was told to buy a blower motor. Need to know where this is located to replace on my 2005 Chevrolet Trailblazer


If your blower works at some speeds and not others, the likelihood of the blower motor needing to be replaced is low. The more common problems would be either the switch or the resister that regulates the motor speed. The resistor is usually located in the air duct under the dash.

All the heater blower speeds work on my 1998 Suburban except the high speed. I have replaced the blower motor and the switch. What else could the problem be? I have seen some writings about a resistor but...


Hello Boco.

In your Suburban there is a high blower relay.
When the switch to high is selected it activates a relay to another circuit that is fused separately.
This fuse in under the hood marked blower fuse 3 which is a 50 amp fuse.
This is most likely the problem.
However, if it isn't then the problem becomes the relay, the switch or a broken wire.
If it isn't the fuse, contact me back here using comments and I will help you with the next step in fixing your heater blower.

Thank you for using FixYa.

SOUNDS LIKE THE SWITCH & OR THE BLOWER MOTOR RESISTOR, ARE THE PROBLEM WITH THE LOWER SPEEDS. SPEED 5 MAY HAVE ITS OWN FUSE, REFER TO OWNERS MANUAL FOR INFORMATION ABOUT THE HEATER/AC FUSE.
