Blower motor not working

several things could cause this, start with testing blower motor relay. then check power from the switch panel. if both OK check wiring and if wiring is good as well then suspect faulty blower resistor pack.

This guide will show you how to check the problem and fix it

2004 Chevy Tahoe V8 Four Wheel Drive Automatic

the a/c blower will not work on position 1-2-3-4 will work on 5 also cool air comes out the driver side but only hot air out the pass side. cked all the fuses all ok

Replace the blower motor resistor-also could be an air mix/blend/mode problems to include vacuum and actuators and the HVAC control module for the cold and hot air problem

thanks, both these problems started at the same time are they interconnected? also is the motor resistor changeable from under the hood. Thaks you very much.

The BMR Its on the HVAC module see item no. 5 below

Okay, so my ac/heater isn't blowing when i turn it on, but it does blow when i am driving. So how do i fix this?

Hello,

It sounds like you may have a blower motor that is going out, when the air is not blowing can you hear the blower motor working? Can you please shoot a quick video with your phone so we can see what's going on? that would be great. You can upload it here with your response.

Here is a guide to help walk you through the replacement with instructions in the diagrams below to show you on your car:

Check out the diagrams (below). Please let us know what happens.

My rear blower began making a squealing noise and then stopped working all together. I'm thinking the bushings in the motor gave out. Where is the rear blower located and how do I get to it?

you have to remove the right rear quarter panel on the inside to get to the motor. If it squealed or squealing the bushing are probably freezing on the shaft and replacement is the option.

Thank you for this post I had this problem and had to replace the blower motor cost me $84.00 all fixed I love this site.

replaced the fan itself. What else would cause it to not come on?

Could be the fan relay or the computer

What fan ? blower or ??????

It is the front AC/heater. You can feel cool when you drive fast but fan never turns on to blow. Replaced the fan but still had issue. Where is fan relay and is computer the one that controls the temp?

youll need to check the new motor by putting power to the motor from the battery to the positive side of the connecter the motor should turn on.follow the power wire from the motor to the blower module. its mounted in the a/c housing on the fire wall.replace it.

The front blower went out today. The 40 amp fusz was fine and I get heat from the rear overhead vents.
Could this just be a relay and where exactly is it?

It could be a few things, the motor itself, blower motor resister, blower motor relay. The way to check is to start at the motor. IF the motor is getting power, then chances are the motor is bad. It is under the dash on the passanger side. If there is no power, then you work backwards to the resister, the relay, then the switch and further if needed.

only the hi speed works on my front blower motor. speed 1 to 4 are inoperatable.. what is wrong

The problem is the resistor. The resistor is on the HVAC module .

I walked out th is morning and the a/c blower was on full blast. Truck was locked on keys inthe house. When I opened truck I could not shut off blower si i pulled the fuse. What's up?

Hi, resistor/relay assembly, found a service bulletin, blower runs all the time. Without being being able to check manufacturer specific codes, or do any testing, that is my best guess. That assembly should be located close to blower motor.

will blow on 1 threw 4 will not blow on 5

Inspect and test the blower motor resistor located -see below

The ac blower is not blowing. It started blowing by it self up and then down now it will not blow at all. The back one still blows.

you need to check for power and ground at the blower motor. if ok then the blower motor is no good.

Were is the blower motor? Thanks so much for the help.

if you look under the dash on the passengers side by the door. try banging on it with it turned on to see if this will jar it and make it work temporarily
