Why does my heater fan only work on a high speed and how do I fix it?
try replacing the blower motor resistor
Resistors control the speed of the AC/Heater fan. These resistors are switched on and off in various combinations to create the different fan speeds. When the resistors burn o…ut your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works. These resistors are near the blower and the blower is beneath the dashboard on the pasenger side. Just have to located resistors now.
Answer . \nThe heater resistor pack is bad. Replace it.. Answer . \nA Blower Motor Resistor burned down and needs to be replaced. It costs about $37 from the dealer an…d is located on the passenger side underneath the dashboard. It is held there by 2 screws and very easy to change. Common problem with Nissan cars.
Defective ballast resistor pack. OTHER : It sounds like it could be the blower motor relay / resistor. I replaced mine today in my 2001 Chevy Impala. It was next to… impossible since I heard that the way to get to the resistor was to remove the blower motor housing and repair it that way. I instead removed the blower motor and got to it that way. The two screws in the back are knuckle busters. Good luck and I hope you have patience or enough money to have someone else repair it.
The blower fans on these cars run very quietly on all but the maximum setting- ensure that the fan is really not working first by holding your hand in front of the vent with t…he fan on low and checking that is it not moving any air.\n Answer \n. \n. \nReplace the resistor pack.
Answer . \n99% of the time it is the heater resistor block, it is a bunch of resistors which gives you the different speeds.\nthis is mounted close to the heater motor, pa…ss side of the car.\nUsual cause of failure: water or snow inside the heater housing.
1996 Mercury Sable. Heater Fan froze. thawed now only have high speed. Can I fix this. I am not sure where to look. Thanks?
Answer . \nYou probably have water tht has entered the heater case through the cowl air inlet, which has damaged the heater blower resister assembly. It is held into the c…ase with two 8mm screws, and is locatted under the glove box area right beside the heater blower motor. Turn on the blower and follow the sound, and you will find the resister assembly right there. I'll bet if you replace the resister assembly, you will have all your speeds back again.
Your 2002 Dodge Stratus ACHeater blower only works when the fan speed selector is on 4 or High Speed What might be the problem and how do you fix?
All or Nothing Blower . The Climate switch on this model is a "Resitor Switch" which means the full voltage is setting 4 ... 1-3 reduces the voltage making the blower motor… go slower... This seems to be a common problem and the only fix is to rplace the switch... However the run around 125.00... Even though this seems to be a reoccuring problem Dodge does nothing about it except sell you a new switch.... 53K Miles on my 2002 and I am into my 3rd switch now.... Don't bother changing the resistor switch because you will rack up too much money in replacing it every 2 months....I have replaced mine 3 x's now at $22.20 a peice from the dealership. The mechanics at Dodge know that this a problem with Stratus' and will tell you to replace the blower and switch, which in time, you will go through this whole process all over again. Chrysler is well aware of the problem and is not willing to do anything about it because of people like us replacing the part a million times & they continue to make money on it. Live with the fact of having heat and a/c on high for the duration of owning this vehichle!
Answer . Check the low speed relay and the resistor at the motor
the mortor is getting worn out some times i have took it out and cleand it out with air and elct-cleaner if that doesnt do the trick i replace it.. The blower resistor may ne…ed to be replaced. It is a small part, It is usually located somewhere behind the glove compartment.
More than likely the blower motor speed resistor is burned out.
My 1998 dodge status fan speed on your heater and front defrosters only works on high speed what can be wrong?
It is your blower motor resistor. It is about a $20 part and you can put it in yourself if you are handy. If not, a mechanic will put it in for $25-$50. I have had this happen… several times to my stratus.
bearing is out,replace motor.
The blower motor resistor pack is bad.
The heater motor speed resister is burned out.
2004 Chevy express van, heater has no high speed, at one time the blower stayed on even when the ignoton was turned off therefor draining the battery,
Switch problem? Cables disconnected?
You most like have a bad blower motor resister.......
