replace blower motor resistor. It is under the passenger side foot well.
Could be, Blown fuse, Bad blower motor, Bad blower motor speed resistor, Bad blower switch,
The blower motor resistor that sits behind the blower motor itself all the way against the firewall.
Control switch on the dash needs to b replaced perhaps?
usually the blower motor resistor pkg. located on or near the blower motor
The blower motor speed resister is burned out.
If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.
If it suddenly stopped working at all speeds, it probably is a blown fuse.
The blower motor resistor is bad.
Normally when some speeds work and others don't, the problem is a bad, Blower Motor Resistor Pack. You will find it somewhere near the blower motor.
figured it out! now i have heat.
When you beat the blower motor, you are probably shaking the blower resister. The resister is what controls the blower speeds and is probably bad or loose.
change the blower motor resistor . this controls the speeds . thanks paul
