You can unplug the blower motor and run a jumper wire to test the blower motor. If it is grounded through the plug you'll have to run a ground wire to it also. Blower Motor tested good. The Problem was the Blower Motor Controller which was located on the firewall just below the Heater Hoses. Thanks for responses to question.
you will find it in the heater box, also where the blower is. it is easy to remove.
The blower switch is the knob you turn on the heater control in the dashboard. If you are talking about the blower motor resistor, it is located in the passenger's foot well area, mounted in the heater box.
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
If a 2000 Grand Am sometimes has the heater blower working and sometimes it won't, the problem could be with the heater relay switch. The heater relay switch lets the heater blower know when to come on and when to go off. In most vehicles this switch is behind the glove compartment. This part sometimes gets corroded from condensation in this area.
the heater blower resistor is bad. located on firewall under heater hoses two 8mm bolts. about a twenty dollar motorcraft part. easy repair.
Check the fuse
the switch, or the blower motor resistor, or blower motor usually it the last two at one time
The heater blower switch and the electrical plug attached to it may be at fault. Remove the heater control unit from the dash and inspect the plastic electrical plug attached to the blower switch, you may see it has melted. The switch and plug is available from your local auto parts store.
The most common cause of the heater blower being on high only is the blower resister failing. The second most common problem is the blower switch going bad.
Blown fuse, bad heater blower motor control switch, bad blower motor, or a bad blower motor resistor pack.
Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
In a 1997 Jeep Wrangler, the relay switch for the heater blower and motor is located behind the dash. It will be directly behind the HVAC knobs behind the dashboard.
Heater motor switch and or the connection at the switch is melted. Also check connections at the blower motor and blower motor resistor for melt down damage.
The blower resistor is under the dash pad on the top of the heater box
BLOWER MOTOR RESITAR SWITCH
it is the switch you use to turn blower up and down.if you mean resistor it is in the heater box next to blower motor
The heater switch can be replaced on a Chevrolet Corsica by removing the three wires from the back of the switch. Put the wires onto the new switch and return it to its slot.
blower motor bad or no power to it chech fuses blower switch blower motor
heater fan blower motor is burn up not working need to replace it could also be a heater relay typically located on the fuse panel that needs replacing could also be the switch on the switch panel
Blown fuse. Burned out blower speed resistor. Faulty blower switch. Bad blower motor.
blower resistor especially if its chrysler/jeep or blower switch
take the old switch out, put a new one in
I have the same problem. what I do is tap on the heater blower (located below the glove compartment in the corner)which will magically make the fan work or remove the two gold Philip screws that hold the cover and spin the fan manually.
The blower "switch" is the knob or lever that you turn or move to adjust the fan speed. Located right on the climate control, next to the temperature setting.
did your heater switch go out all of a sudden or did some work like high work and low not work? if some worked your blower resister is most likely bad under your glove box
