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.

What does the blower resistor do?
It gives you all the blower speeds except high.
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 would cause a blower to work and all speeds except High in 2002 Chev Trailblazer?
This is more than likely caused by the actual fan switch. As I am English, I have no idea what a Chevrolet Trailblazer is, or what it looks like even, but there are things which are common to all or many vehicles.
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
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.
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.
Why would all speeds work on the fan except for 5 in your 2005 trailblazer And also now your headlights flickerdim at night faintly?
Could be the blower motor resistor. If the other fan speeds start to disappear over time then you will have to buy the resistor. Cheap and easy fix in 20 minutes. Headlights flickering are probably an indicator that your battery is getting weak. www.trailvoy.com All the answers for your Trailblazer with pictures and instructions!
2002 trailblazer blower motor does not blow speeds 1 through 3?
The blower motor speed resister is burned out. This part is available from your local auto parts stores. The resister is located in the engine compartment, on the firewall, on the passengers side.
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
1988 Toyota truck blower motor speeds won't work on low speeds?
The blower motor speed resister is burned out.
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.
If the blower started going out on the lowest level and over several months continued to the highest on an 2002 Trailblazer Would this be the motor itself or the resistor?
Based on the symptoms suggest a progression of failure in the various speeds, I suspect that the blower motor itself is probably OK, and the problem is a failure of the blower "speed control RESISTOR PACK." The speed control resistor pack is usually located on the plenum chamber [the "box" usually located beneath and/or behind the dashboard above the right front passenger's seat floorboard.
