It is between the fan and the firewall. The two wires plug into the side of the fan. Two screws against the firewall do not have to come out, just loosen. Easiest with a quarterinch drive flex extension. It is located between the blower motor and firewall, right against the firewall. Three screws hold it up to the bottom of the housing. The back two only have to be loosened as they are very difficult to get to. Follow the two wires from the fan and that is it. It's a tight fit.
Either than switch, the resistor, or the relay is bad. On my 1999 Buick Century, the blower motor quit working on the three lower speeds, and then went out completely. When the resistor goes bad, the lower speeds quit working. My blower motor was squealing, also. After I replaced the blower motor and the resistor, I tested it and found the blower worked great on every speed but high. It turned out that there is a separate circuit for high speed, and the fuse was blown. I replaced the fuse for the high speed, and the blower now works on all 5 speeds. Replacing the blower and resistor was difficult, but not as bad as expected, thanks to help from this site.
In general the heater blower motor speed resistor is located in close proximity to the blower motor.
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
heater blower resistor has to be replaced. you have to remove glove boxthe resistor is to the right of the heater blower moter
i have a 1998 buick century and my blower motor is under the passenger side front wall inside.I found out that the blower motor resister was the problem.if it works on high speed only,replace the resistor first.it's cheaper but harder to get at.
toyotas have a resistor bank in line with heater motor each speed has a different value resistor. there is no resistor on high speed. it is located on passenger side in heater duct I thank it has two screws holding it on when you get it out you will see the resistors burned
The blower motor speed resistor is burned out.
They generally locate the heater motor speed resistor nearby the blower motor because the resistor depends on the blower to keep it cooled.
Heater motor speed resisters are usually located close or nearby the heater motor.
The resistor block or blower motor resistor is used to control the speed of the blower motor. That is how you get the lower speeds on your air conditioning or heater. The higher the resistance the lower the speed of the motor.
The blower motor speed resistor is burned out.
the first part I would look at replacing is the fan resistor this may be a circuit board or a assembly of three coils which regulate the fan speed. This resistor may be under the dash where your blower is located or under the hood next to your blower. Hope this helps you.
