SOURCE: blower puts out too many amps

I never read that the fuse was blowing in any of the descriptions, but if we are going to jump ahead and suppose the armature is shorted, wouldn't it be easier to just pull the plug off the motor and replace the fuse and turn the motor switch on and see if the fuse pops after we have eliminated the motor. If fuse does not blow, the motor is bad. If fuse blows, you have a short somewhere.

In my experience, armatures usually fail open and the motor simply won't work. I still stand by my suggestion of step by step methodical troubleshooting rather than buying the parts first.

SOURCE: Blower Fan will not blow on 1995 Chevy Suburban

It sounds like your blower motor may be bad. I don't know if you know how to check power at your blower motor plug, but you can use a volt/ohm meter or a test light. If you have power (12VDC) , your motor is most likely bad. There is also a resistor block module which has 2 resistors on it. It controls the motor speed basically by restricting the power by directing it thru one of the resistors. The higher the resistance, the slower the motor turns, thus the 3 speeds for the motor. The resistor module is mounted on the blower housing and has 2 screws holding it in with a small plug connected. It is just about straight ahead of the passengers left knee.
You can get used motors from a junk yard pretty cheap.
Good luck

SOURCE: All the heater blower speeds work on my 1998

Hello Boco.

In your Suburban there is a high blower relay.
When the switch to high is selected it activates a relay to another circuit that is fused separately.
This fuse in under the hood marked blower fuse 3 which is a 50 amp fuse.
This is most likely the problem.
However, if it isn't then the problem becomes the relay, the switch or a broken wire.
If it isn't the fuse, contact me back here using comments and I will help you with the next step in fixing your heater blower.

Thank you for using FixYa.

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

    My Heater Blower motor stopped working on my 2007 Chevy Suburban


    you will need to check 3 places for this. 1 check the plug going to the blower motor for being hot and melting.2 check the plug going to the blower motor resistor for being hot and melting. 3 check behind the heater control head itself for being hot or melting.chevrolets are bad about these three places not making good contact and melting the connectors.

    Heater Blower won't work


    Find the blower motor on the passenger side just above where the passengers feet would be. You may need to remove a panel (fairly easy). You will see a round metal housing about 4" in diameter. Turn on the ignition key and blower motor. Then tap the housing with a small hammer or a screwdriver. If the blower comes on.....replace the motor. If not, find the wires leading to that motor, undo the connector and check for power and ground in them.(You did check fuses first...right?)
