Hello there:
there could be a couple of things wrong try checking you're blower motor to make sure you are getting any power to that point with switch turned to one of the lower setting if no power it could be the switch in the dash if there is power than it will more than likely to a bad fan blower...hope this helps you out sincerely D.Jones...

    I had the same problem , you need to go buy a blower motor resistor. You can look up on how and where to install it at on you tube.

The fan in my 2001 chevy tahoe doesnt work on 1 or 2 but 3 through 5 are fine


Usually a sign of a faulty blower resistor. The resistor changes the amperage of the circuit to change the blower speed.
You can look the part up online to get a visual.

05 GMC sierra heater blower stopped working. It used to work on setting 1-4 but lost 4 a couple weeks ago and now none of them work. Is this a bad blower , resistor or both?


The resistor is most likely bad but should still work on the highest setting.Would check pigtails to the resistor and to the blower motor for burnt or discolored wiring.You can try tapping the blower motor and wiggling the wiring harness too see if it will work on the highest setting. It is possible that the blower motor is bad as well typically when you lose the speed selection it is the resistor but you should always have high speed.

I have a 2003 Chevy Tahoe . The heater and a/c fan only works on the highest speed #5. How do you repair this problem?


Check the blower motor resistor.It is on the passengers side by the blower motor under the dash.The resistor is connected to the blower motor and controls the blower speeds.They are known for going bad.Also check the connectors because they get hot and will melt.If they are melted then you will have to replace the connectors.You can get these from the dealership.Replace the blower motor resistor too.Hope this helps.Good luck.

Blower motor on my 2003 Tahoe only works in position 3 and 4


CHECK THE CONNECTOR TO THE BLOWER RESISTOR. IT USUALLY BURNS TO THE RESISTOR. YOU WILL NEED TO REPLACE THE RESISTOR AND THE CONNECTOR.

Air conditioning blower speeds


sound to me like you have a blower fan problem. its not uncommon for the fan to "burn out on the lower speeds due to those being the most commonly used speeds. double check with your mechanic to be sure. blower motors aren't hard to replace but the prices vary alot based on type.
