Sounds like a bad blower motor resistor block.
usually the blower motor resistor pkg. located on or near the blower motor
The blower motor speed resister is burned out.
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.
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
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
If you have no blower speeds at all check the fuse, then check the blower motor switch and electrical plug for a melt down situation, then check the blower motor itself.
Blower fan resistor controls electric current to the fan motor to maintain different speeds.
Probably the blower motor, wiring to it or control switch
If the blower works on some speeds and not on others, you may not need a motor. Instead, you may only need a new blower motor resistor.
Probably the blower motor speed resistor is partially burned out.
Not always, but 99% of the time this is a sign that the Blower Motor Resistor Pack is defective. Replace it.
Only for the high speed. The lower speeds are controlled with the use of a blower motor speed resistor.
replace blower motor resistor. It is under the passenger side foot well.
Not knowing what year S10 you have, you can generally find the blower motor high speed relay nearby the blower motor on the firewall. The resister for the other lower speeds is also found close by the blower motor.
Under the dash on the passenger side in front of the blower motor. You will see 5 wires going into a plug held in by 2 screws. That is the blower motor resistor.
The blower motor resistor that sits behind the blower motor itself all the way against the firewall.
If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.
sounds like the blower motor switch; since it is working at the lower speeds I'm guessing, then it's not the resistor (if the resistor was gone then it wouldn't work at all). Got a question for you in return. where is the freaking blower motor at on one of those. cant find mine to save my life.
If all speeds do not work, suspect the fuse, the switch, the switch connector or the blower motor. If only high speed works, suspect the blower motor speed resistor. If low speeds work and not high, suspect the blower motor relay.
The heater blower motor is on the interior passenger side. It is kind of a round shaped housing facing the floor.
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.
The blower motor resistor is defective. They go bad when the blower motor pulls to much amperage.
If you have checked the blower motor and it does function when power is applied then I would suspect the Blower Motor Resistor Pack is defective. It is also possible the blower motor speed control is bad, but highly unlikely.
