Hello schmedium.
This is a common problem on all vehicles, more so on General Motors cars.
The brushes on the fan motor are worn and are not making contact.
When you hit a bump or move the motor it makes the brushes contact the armature and begins to run.
The motor is mounted to the heater box just above where the passengers feet would be.
Relatively easy to replace if you can twist yourself up under the dash.
I would suggest getting a Delco brand motor with the fan blade attached.

Thank you for using FixYa.

Why is my heater not blowing hot or cold air? sometimes if I bang on the dash board it comes on


It sounds like your blower so buy a new 1 from Auto Zone and then install it & if it works problem solved. If not return it for full credit & buy the Relay Switch & try that bc it regulates the Blower Speeds of 2 & 3. See if that works. It is near the Blower on the passenger side under the dash and fairly easily to get to. Hope this helps. Jim

I have a '03 Dodge Grand Caravan Sport AWD that the heater only blow hot air when going down the road. Van has a new radiator and new thermostat. Sometimes the blower will not kick on for a few


If the problem is a lack of air flow from the vents, and you suspect the blower motor is not running at times, you would need to test the blower relay and blower motor for power and ground when it is not working.

I have a 2004 Impala. when I turned off the ignition myheater blower stayed on what can i do tofix it cheap?


More than likely the resistor for the heater motor is causing the problem
it is located behind the heater motor under the dash on the passengers side. If the heater motor is making noises it may be drawing to much and caused the resistor problem.

The heater doesn'twork all the fuses I can find


You're probably right on the fuses, but I'd double check them first. Kick panel (drivers) fuse box (probably third fuse, 7.5 amps, top row, if you have a 3.0 spare fuse in the first socket). That's the heater relay fuse. Take it out with the provided puller (in the fuse box at the back) and look carefully at the wire between the two feet of the fuse.
I hope this is helpful. Diagnostics on a blower are tricky.

The heater blower on my 2003 GMC sierra wont shut off


i had the same problem. depends what kind of trim model you have. but if you look on the passenger side floor right under the glove box is where your heater unit is. if you take off the cover to it. their will be a little squarebox looking thing with 2 - 3 wires coming out of it and goin to the blower motor unit . Tap the square box with a screwdriver while your blower motor is on off mode. it should shut off if you give it a couple good solid taps. dont be afraid to hit it. that little square thing might have to be replaced if it turns off when you hit it. or just may have to be cleaned.
