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.
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.
You've got to use a test light to see if there is electricity getting to the switch. First check to see if it's getting past the fuse - then to the switch with the switch off - then through the switch with the switch on - finally to the blower motor.
The heater switch is located in the middle of the car in the 1998 Ford Taurus. It is either above or below the radio.?æ
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 the fuse
Blown fuse. Burned out blower speed resistor. Faulty blower switch. Bad blower motor.
There is a relay switch on the back of the main selector switch. If this part goes bad many times the blower will either work on high only or will not work at all. Replace this blower switch, more than likely this is the problem.
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.
Accessing the dashboard heater controls on 1996-2005 Taurus/Sables requires the integrated radio/heater control dash panel to be removed. Not hard at all - it's the same as removing a traditional Ford radio. See "Related Questions" below for detailed instructions.
the switch, or the blower motor resistor, or blower motor usually it the last two at one time
Fuse-switch-bad connection-blower relay-fan motor. I would check the fuse then look at the blower relay. they go out quite offen on Dodges
