There is a known problem with the wiring in the system, pull the connector off the blower motor and see if it looks discolored and burnt and the terminal inside are discolored from heat, if they are you will need to repair the connector and also replace the switch and the connector to the switch in the control panel. There may be a factory service bulletin on this, check with the dealer.

SOURCE: Blower motor or resistor?

If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.

it's the blower motor resistor , it's behind the glove compartment, just make sure you disconect the neg. for battery first, open the glove comp. and pull the rubber stops towars the center so you can let the glove comp. hang all the way to the floor , the resistor it's in front of you, disconect the two conectors there's one big with 6 0r 8 wires coming out and another with only two, take them out by pressing on the side of each one, remove it , put the new one on , conect the battery and your done. it's about $ 13.00 at o'riellys auto parts .

I hope this fix yor problem.

SOURCE: Blower motor or resistor?

Yes its the blower motor resistor.

More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.

The blower motor is under the glove compartment

You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

The blower motor resistor is what controls the speeds of the blower motor. It is under the battery tray.. you have to remove it to see the resistor, and there is 1 bolt holding it to the truck, with a (2 wire) plug going to it.

2005 Trailblazer EXT. Blower speed control not working...


Problem with blower motor is the blower motor resistor. They are usually located next to the blower motor, a couple of screws and a couple of plugs and your done. Autozone sells them for around $30 each. Wipers you may want to check for relays under the hood in the fuse block. There may be 2 relays 1 for low and 1 for high. I have switched relays from other working accesories and got wipers to work. Sometimes bad connection.

Blower motor only works on HI speed


I had the same problem with my 2002 Safari. The blower resistor/relay pack (mounted on the ductwork below the blower motor) in the engine compartment went bad- poor design. A replacement unit (about $120) is available from the dealer. Removal of the coolant overflow / WWasher bottle is required, as well as enlarging the the mounting opening. A Chilton 1985-2005 Astro/Safari manual has the diagrams...
