Why does the blower motor on a 2001 Chevy Suburban work on all speeds except the lowest or 1?

Blower motor resistor pack is failing or the switch itself is bad. Answer above is correct - it will usually be the resistor pack, part name "Blower Motor Resistor." I got the part at Pep Boys for 1/2 Chevy/GMC dealer price. Here's how you put it in: 1. Remove plastic shroud covering blower motor in front passenger footwell - three 9/32" bolts. One of the bolts is tricky and is closest to the center of the vehicle (the driveshaft hump makes it tough to get the socket in - have patience, you'll get it). 2. Remove two bolts holding resistor in place - 7/32" bolts. 3. You need to remove the blower motor cover/shroud to access the 2nd wiring clip - 7/32" bolts. I had trouble accessing the front (front of vehicle) screw on the cover, but I was able to move the shroud out of the way enough to access the clip by only removing the rear screw. 4. Connect electric components 5. Replace covers/shrouds Happy wrenching!

What does the blower resistor do?
It gives you all the blower speeds except high.

More than likely the blower motor resistor pack is bad, although it can also be the switch itself.
How do you fix a1999 Chevy Suburban with no power to blower?
With no speeds at all, check the fuse, then check the blower speed switch and it's electrical plug.

Could be hi-speed fan relay or secondary winding in blower motor

The blower is a multi speed unit.
When the blower does not work on all speeds is it the blower motor?
usually the blower motor resistor pkg. located on or near the blower motor
Why does my blower fan run at all speeds except max Like the opposite of the normal resistor failure?
wiring fault. at max speed the resistor is bypassed
What could be causing the heater blower motor to work only in the full blast switch setting - 1988 Suburban?
most vehicles have one circuit(and one fuse) for the first 3 fan speeds and a separate circuit and fuse for the highest speed.AnswerCHECK THE BLOWER MOTOR RESISTOR
What can be wrong your 1998 suburban fan works on all speeds except hi?
either the fan switch is faulty, or the fan itself is faulty. most likely to be the switch

Heater blower resistor is what controls the low medium high speeds...

The Blower Motor Resistor Pack is defctive. Replace it.
