SOURCE: heater blower motor works intermittently

I would replace the blower motor, this sounds like a motor brush problem inside the motor itself.

SOURCE: i replaced the blower motor

This sounds like it could be 1 or 2 different problems. The first is the control head. Obviously if the control head is malfunctioning it is not sending the proper signals to the the blend door. If the control head is ok, then it could be the blend door itself or possibly the actuator. Unfortunately, you may have to remove the whole dash to get at the actuator or blend door

Why is air coming from all three areas (vents/floor/defrost) regardless of setting?


There is actually two blend door actuator that control the opening and closing of your vents. Ine is located under the drivers side dash board. The is on the passengers side. Both are electric and I didnt have the money to replace them so i removed them and turned it with a pliers to allow heat to come out of bothe sides of the vent. Then come summer flip the little bar back the other way to A/C
Hope this helps

Blower fan not working.


Possible speed control is open circuit or the fan motor. Check you have supply to the switch/motor.

I have a 2002 Grand Am SE, my heat works fine, temperature wise, but doesn't flow out of my vents very well. Whenever I turn the heat on I hear a loud humming/vibrating sound coming from my blower...


I had a very similar problem on a Buick recently. Like mine, your blower's fan blade assembly may have come loose from the motor shaft. There is a very small washer type clip that holds the fan blade part to the motor's shaft. Usually the whole blower assembly is pretty easy to get to and take off...usually. A lot of GM cars had the assembly accessed from the firewall behind the engine. You would need to pull the blower motor out and check the fan assembly.

Heat or A/C does not work in my car?


Either you have a blower motor FUSE that has gone bad "typically the problem" or you have a burned out blower motor. Usually the cause of a blown or burnt motor if not a Fuse, Is caused by the vented air from outside letting debris like sticks or leaves,acorns etc. enter the fan box. If ANY of the mentioned items get caught in the "blower box" then it will usually blow the fuse and or burn up the blower motor. Start in your fuse box and look for a burnt fuse and replace with same size fuse. If it blows the new fuse quickly then you have debris in "Blower box" that will have to be removed before adding yet another fuse. I have had the same problem and I found a bunch of leaves in my "Blower Box". I removed the leaves and replaced the burned out fuse. And I have had no more problems with the blower motor blowing air.

The blower motor stays on high all the time. A/C works but will not come out dash vents, comes out defrost and changes to floor when I accelerate. Thanks for your help. Cecil


Your problem with the blower motor only running on high is caused by a defective blower motor resistor pack. Replace the resistor pack. The problem with the vents is not related to the blower motor, and is caused by a problem with the vent controls. I suspect you have a vacuum leak under the dash.

I have 2001 Volvo S80 and the heater and AC comes on for a minute or two and then shuts off. The dealer said it was the blower mower burned out. How can that be if it works now and then?


Assuming that the dealer is correct and isolated the problem down to the blow motor...
it IS possible for the motor to work intermittently due to heat buildup. Malfunctions due to heat will call the motor to run fine for a bit, and then quit when the motor reaches a high enough temperature to cause a malfunction. It would then quit working until it cooled back down, and repeat the process.

Whether is it just dead, or it is intermittently dead, for all intensive purposes, the motor is no longer usable and needs to be replaced with a new unit.

Blower for heater stopped


Remove the hush panel under the dash and unplug your blower motor turn the knob and see if its getting power. If it is replace the blower motor. If your heater seems to work on high but not the other 4 settings. replace the blower motor resistor and pigtail (same general location as blower motor)

Vent fan only works when set to 4


Hi.....
On your Vehicle the problem for the FAN speed is NOT the FAN switch.
99.9 % of this problem on cars is the BLOWER MOTOR RESISTOR.
The blower motor resistor give the speed to the Fan.
But on High speed the switch make a By pass of the switch using a Relay for the high speed.
The Blower motor resistor, is located Beside of the Blower motor On the passanger compartment.

If you replace the blower motor resistor you have 99.9% of this will solve your problem.

I'm a Mechanic.

I hope this help on your problem.
Thank you for use fixya...
