What is wrong with my Heater Blower ?
The heater blower works most of the time. When I start the car first time in the morning' the blower works. When I shut the car off , and then start it up after an hour or two, sometimes the blower will start and sometimes it won"t. After driving for a while, sometime it will start blowing. If it doesn"t start by itself,sometimes if I tap the area where the blower is, it will start blowing.
Bad conection or the blower motor is going bad would be guess
armature may have a flat spot in it. When you tap it or hit a bump it will move it a little and get it off the flat spot
Thank you. I will look at a bad connection or replace the blower motor. I thougt that it could be a bad Resistor Module. Is tha possible?
No a bad Resistor module will either work or it won't
A 2002 blower motor is over ten years old. The brushes are worn down and get stuck in the brush holders. Tapping the motor breaks them loose. Replace the blower motor.
I have a similar issue with my 2000 Park Avenue. I took the panel off behind the dash, found the resistor module, and the wires there seem to be loose. If I push on them the a/c works for awhile. Then it vibrates and stops/starts intermittently. It seems the connector to the resistor is bad on mine. Looks like some of the wires may be making a bad connection inside the plug. I'm trying to find the plug but it looks like my only option may be to buy a new resistor. Check your wires. Could be the same problem. It gets pretty hot at that connection, and my plug has a melted spot.
Please post if you find a solution.
