Heater motor problem!!!!

When you turn on the blower fan motor, sometimes it will run and sometmes it doesn't. When it doesn't you can give it a smack with your hand and most times it starts up, but not always.
I have changed the control panel, same problem.
I might add that it seems that the colder it is the more times yoou have to bump it. also tried healys didn't fix the problem?

Hi my name ia Allen!

This is a tough one, because when something is still working its hard to penpoint the problem.

This can be a lot of things, one a blower motor resister, two blower motor relay could be going bad, three could be a wiring problem.

But here is the most common problem with that year. Under your hood on the left side as you are facing the vehicle, back on the firewall there is a connector that burns up on the blower resister.

Here is what I need you to do, turn the key on with the blower on high so you can here it, you need to wiggle that connector and listen for the blower motor to go of and on. If this happens, you will need a resister and wiring pigtail, because the wiring will have to be replaced and the resister will have to be replace, but we can get to that when we get there.

Let me know what you find, waiting for your reply.

    Here is a diagram of what it looks like and where the resister is located. If you click on the picture you can make it larger by clicking and holding the mouse button and dragging one of the little boxes to make the picture bigger. I can assure you this is what your problem is and it is repairable.

Heater fan not working

Smack it and see if it comes on. If it does then the motor brushes are bad. If it does not come on, check the fuses. If the fuses are ok, check the voltage on the plug to the motor.

Blower control

Check connector at the blower motor. The ground burns up in the connector. Also try this turn the blower motor on speed 3 then smack the bottom of the blower motor. If it starts blowing the brushes in the motor are worn out. Replace the blower motor.

The switch is the thing on the dash with the knobs about 220 dollars. The switch(resistor) that controls the fan speed is under the dash on the far right under by the fan 20 dollars. I would check that power is getting to the fan or unplug and run jumper wires to the fan if it doesn't turn on the fan is bad 40 dollars. There is a blower motor relay under the hood in the black box by the battery or on the passenger side looking in the top it will tell you what relay and fuse is for what circuit. Sometimes they put a spare in there marked spare if not use an identical one from another circuit 14 dollars. If this helps please rate it thanks

My heater will not blow anything unless im driving then i get hot air i changed the passenger filter and a couple fuses and still nothing i own a 2003 chevy impala 3400 engine

Try giving the blower motor a rap with a hammer handle or long screwdriver while it is on. Sometimes it will get it started. That is a sign that the motor brushes are bad and the motor will need to be replaced. The smack jars the contacts just enough to get it in motion and it will continue to run until you shut off the car.

Heater fan blowing intermittently or not at all

Most likely it does, if you can hit the motor and it will run. I can't say for sure but you might want to chk. to see if you got a heater blower motor resister. There located (if its got one) around the heater motor and it controls blower speeds, might be worth checking out.
