What causes the heater blower motor in an 2002 Trailblazer to work in speeds 1-4 but not in speed 5?

2002 TB seems to have problems with the blower motor resistor. Its located under the glovebox. Must remove the glovebox door to access it. Parts stores can't keep them in stock! should be about $20 to replace. Also, I believe fuse #35 in the engine compartment fuse block controls the blower on "5" high setting, so check that first. Either the blower motor speed switch or the resistor pack are bad.

What causes the heater blower motor in a 2003 Trailblazer to not work in speeds 1-3 but works in speeds 4 and 5?
Probably the blower motor speed resistor is partially burned out.
What is a heater blower resistor?
Heater blower resistor is what controls the low medium high speeds...
What causes the heater blower motor in an 2002 Chevy silverado not to work in 1-2-3 speed but 4-5 speeds work fine?
the heater fan resister,it is or should be on inside or on outside heater box.
How do you replace a heater switch in a Trailblazer?
This is not a common failure. The more likely culprit is the blower moter resistor that controls the fan speeds. Very simple to fix yourself and about $35 for the part. To get more info about this or other Trailblazer '02 and up questions join our forum at www.trailvoy.com
What does the heater resistor blower effect on a 99 mercury sable?
A bad heater blower motor resistor would effect one or more blower speeds other than high.
Where is the switch for the blower the located in a Chevy Trailblazer?
If you do not have fan speeds it may be a fuse or the blower motor resistor. For help with the issue visit our enthusiasts forum at www.trailvoy.com
You only have three speeds out of five on your heater motor where could the problem be?
blower resistor especially if its chrysler/jeep or blower switch
What would cause the heat and ac blower not to work on 2006 trailblazer?
if all speeds do not work id say is a fuse, but if you just dropped one or two speeds. replace the blower motor resister. sells for $60.00 at the dealer.
You are not getting any power to the blower motor on a 2005 Chevy trailblazer?
If you have no speeds at all, including high speed and you have power at the fuse and the fuse is good, I would suspect the heater blower speed switch and or the electrical plug to the switch is cooked. If you have high speed only and the rest are dead, I would suspect the blower motor speed resistor.
How test Chevy Trailblazer blower switch?
if you lost one or two fan speeds you need to change the blower motor resister. it sells for around $60.00 at a dealer only.
Cause for low speeds on blower fan 1994 ford not to come on high speed works?
Resistor on the heater blower motor has failed
Why does the blower motor on 2002 trailblazer work on all speeds except the lowest?
More than likely the blower motor resistor pack is bad, although it can also be the switch itself.
