SOURCE: The blower for my heater isn't working. How do I fix it?

Yes, there is a fuse. NO, there is no way possible for the fuse to be the CAUSE of your blower not working. Yes, the fuse may be blown, but fuses do not just go around blowing themselves out to make your day miserable. If the fuse is blown, there is a reason for it. Fuses do not cause elecrical circuit failures....electrical circuit failures cause blown fuses.

Nobody can tell you what is causing your blower to not work without first DIAGNOSING your blower motor circuit. There are probably some people that would tell you to just replace the blower motor. However, I would not recommend that because "diagnosis by parts replacement" can be VERY COSTLY. You might get lucky and it will be the blower motor, then maybe not. If not, then you will be out the cost of the blower motor and still have no air.

If you check for power and ground at the blower motor electrical connector and all is well, then it is the blower motor. If you check for power and ground at the blower motor connector and either power or ground is missing, then you will have to trace the rest of the circuits to find out where the failure is.

SOURCE: heater/AC blower doesn't work at any speed

I would start by looking for a fuse that blew out. Depending on the vehicle, it could be clearly labled. fuse could be under the hood, or under the dash. it the fuse is good, next, could be a short, and most likely in the motor itself. What kind of vehicle; year, model? Dave

I have a 2004 Impala. when I turned off the ignition myheater blower stayed on what can i do tofix it cheap?


More than likely the resistor for the heater motor is causing the problem
it is located behind the heater motor under the dash on the passengers side. If the heater motor is making noises it may be drawing to much and caused the resistor problem.

1998 Mercury Mystique heater blower motor doesn't work. Have replaced everything and checked both fuses (both good). What next?


Don't know how the ABS light would be related to the blower motor, you said you checked everything - did you check the blower motor circuit for power and ground with a meter or a test light ?
Is the resistor getting power from the relay ?

Heater blower works just don't get any air at all


The heater blend door actuator is not opening the door.Check for power at the actuator and if you have power at the actuator and its not working then replace the actuator.These actuators are a well known culprit of this problem.You find the actuator behind the glove box it will have a small arm on it that operates the heater blend door.

A/C and Heater Problem


Well,you eliminated the resistor,so it probably means the blower motor has shorted out.Either that or something has gotten into the blower wheel and jammed it. If you can bypass the resistor and just put 12 volts into the motor,do it.But don't hold it long,as a direct short can cause a fire without a fuse to blow for safety.
In other words,prepare to buy a new heater blower motor. don-ohio

I have a 1998 Plymouth Grand Voyager. Last week, the rear blower stopped working and the brake lights no longer function. All other lights work. The front blower works just fine. All fuses are...


The rear blower and the brake lights might not be related troble. The rear blower has a ballast resistor that can fail and it's next to the blower motor in the rear heater housing. The blower motors are also known to go bad so wrapping on it with it turned on might( wake it up) and it'll start woring again as a poor connection shaken or the worn motors brushes shaken down where they make connection again. Then you say the rest of the lights work do you mean that the brake light bulbs come on with the hazard swich entergized? or do the rear lights just light yellow turn lights only? I'd check or even replace the brake light buld=bs before I'd do anything else.their are other things that don't work if the fuses were involved and the same goes for the heater rear blower as the front blower uses the same fuse.

I need to know which fuse for a 2002 ford tauras for the heater or blower


There are 2 places that you can look at. In the fuse panel located inside the vehicle in the number 3 position (see picture below) is the fuse for the blower motor relay coil & in the number 3 position is the blower motor relay itself. This should be in your owners manual if you have one. If you don't have one and need a copy, you can email me at csautomotivecars@att.net with your make, model, year and what you need and I will be happy to email you a copy. don't worry no cost to you. Anyway, I hope this helps and good luck.
