Try tapping the bottom of the blower motor with the key on and the switch set to high. If the blower starts to work replace it.

SOURCE: heater blower motor works intermittently

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

SOURCE: my 1998 astro van blower motor only works on high speed.

No the motor is not bad or going bad, the heater blower motor resister is bad, thats regulates the blower speeds, its located under dash by heater motor 2 screws hold in heater box with a electrical plug to it.

SOURCE: blower motor resistor

Two bolts a little neck twisting 5 mins...
Look under the dash follow the wiring from the blower any two of them will lead you to the resistor. It's in the air box about.

You most likely need to replace the ignition switch. Sounds weird, but check out other posts. It works.

SOURCE: Blower motor on 96 Isuzu Rodeo does not blow on

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.

I have no heat or air blowing out of my vents. Any ideas?


still nothing,????
why do this backwards. ??
or not using simple diagnosis>?
so really you failed to state the beginning symptoms?
was it just just noise. or noise and no blow.
or the noise is gone,, but my fix broke the blower.
there will no heat not moving, if the blower is dead.
get heat , moving in non circ, mode.?
sure i bet you do an that is SOMETHING.
does the blower make sounds like a normal blower, then if no air flow
the dampers are bad.

blower silent? on all speeds, , do say so.
blower works only on high (sounds) ?
if the blower is running, surely you can hear it spin fast.
and there is no flow, the damper is bad or the blower fan blade set screw
is missing and or loose. did you check that screw first. before.
replacing the motor? id not ever skip that step.
we can not help you ,with no facts or symptoms but still nothing.

99 Dodge durango heater not working


The blowers ion the back have there own blower motor. The front has it's own. The resister controls the range the blower motor runs on,( low, medium, high). If the blower motor is not working it may be the motor itself. Was the fuse checked:?

We own a 2001 Jeep Grand Cherokee and the a/c and heat are not blowing at all, only the defrost works on low,


have the blower motor resistor checked it may be bad causing air not to blow, you will get a little heat at defrost because heat rises and thats the high point, the blower motor is not working check that resistor.

Car heat blower is not blowing heat/air into the car


it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.

Limited heat


first, check the fuse for the blower motor. If ok, you may have a bad switch or bad blower motor. If you are a techie, you should jumper 12 volts to the blower motor hot terminal. see if it blows then. You also have a blower motor resister that gives you the 4 blower speeds, but usually when it fails, you have high speed only.

good luck

Heater control only works on high


You need a blower motor resistor,and the heater blower motor should be checked for high amp draw. check Napa for the part or go to Dodge..prpbably about 60.00 dollars.

The problem is the blower motor speed control resistor, it is located near the blower motor in the housing.
