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?

Re: heater motor 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.

heater or 'blower motor's are prone to bearing failure,which can cause interference between fan & heater box;stopping,or slowing fan.consult a shop manual to DIY,or have a mechanic check blower motor .[I have found a stockpile of acorns causing a problem a time or two!!] Hmmm,Summer OK;Winter.........O nuts.......good luck!
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
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.
if you are talking about the engine electric cooling fan..it will run after car is turned off until temp goes down then it shut off..unless you're talking about the heater blower motor..then i would look in the engine compartment passenger side firewall for the heater box ..on the box there is speed control resistor for the heater fan speed..that might be shorted.if not fan switch on dash..give more info next time..it makes it easier answer with more info
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.
