Question about 2002 Chevrolet TrailBlazer

1 Answer

The blower on my 2002 Chevy Trailblazer was not working, I replaced the resistor and it worked on settings 1,2,4 &5. when I replaced the resistor I noticed that one of the leads was burned and the wire block into the resistor was partialy melted. The blower has stopped workin again. I looked at the new resistor and the situation is the same as the original. I did notice when I replaced the resistor and tested the system that the resistor was hot to the touch. Is this normal? Could the situation be remedied by changeing the wire block as well?

Yes the resistor is going to be hot to the touch, unless you run the blower on high which bypass the resistors to give the blowers a full 12 volts. You could try replacing the wire block and harness just to make sure there is no short in the system that is bleeding off and grounding. 
Good luck and hope this helps.

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.

The blower fan only works on the high setting, #5 - what needs to be fixed, 2002 trailblazer

There is a blower resistor module by the blower motor that goes bad.You need to replace it.Also check the connector out very carefully because they get hot and like to melt.If it is melted then you will have to order a connector from the dealership.This will take care of your problem.Hope this helps.Good luck.

Heater control fan only works on speed 5. Removed heater control, what does the resistor look like? I'm asuming it's not a regular electronic resistor right?

Your looking for the blower resistor. Its on the passenger side under the dash. Two of the wires go the the blower motor. The wire connector and the resistor can burn or corrode. The replacement is easy two screws hold the resistor in and the connector can be replace with **** connectors.
