You'll likely need to replace the blower.

SOURCE: 2002 Ford Taurus blower fan only works on high

fords are notorius for faulty fan switches, you will need to get a new one, but it will probably fail in a year or two.

SOURCE: my 1998 astro van blower motor only works on high speed.

No the motor is not bad or going bad, the heater blower motor resister is bad, thats regulates the blower speeds, its located under dash by heater motor 2 screws hold in heater box with a electrical plug to it.

SOURCE: HEATER BLOWER MOTOR ONLY WORKS ON HIGH SPEED

THERE'S A SENSOR UNDER THE PASSENGER SIDE OF THE CAR UNDER THE GLOVE COMPARTMENT YOU HAVE TO LOOK WAY UNDER JUST LAY DOWN ON TOP OF THE MATT IN FRONT OF THE PASS SEAT IT HAS 2 SCREWS ON IT UNPLUG IT THEN UNSCREW IT TAKE IT TO THE DEALER IT COST ME ABOUT 30 TO 50 DOLLARS BUT THAT WAS THE PROBLEM I HAD. GOOD LUCK

SOURCE: ONLY ONE BLOWER SPEED

You need a new blower motor resistor module, it's screwed into the side of the blower housing.3be2c96.jpg

SOURCE: Blower motor on 96 Isuzu Rodeo does not blow on

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.

Why is the ac cold but doesn't blow high


It's the armature, high speed fan motor or maybe the switch could b broken, I'll look at it, 9494545252

01- Dodge Caravan AC Heater Control it only works on high none of the speeds work when I rotate the switch from low to high. Is this a swith problem or a motor problem?


Most likely neither. The most common cause is that an electrical device called the blower motor resister block, has failed. This device provides all the slower speeds. It is generally mounted in the HVAC [Heating, Ventilation & Air Conditioning] box, very close to the blower motor. FYI, we mechanics call the fan motor inside the cabin the blower motor. The electric fan motor behind the radiator is called the cooling fan motor.
If the resistor block is OK, then you have either a bad fan speed switch or a melted electrical connector at that switch. 95% of the time, the resister block is the problem.

I have a 95 jeep cherokee and the heater/blower/AC fan only works in the fastest position. Any idea what is causing this?


Blower motor resistor.
Look under the passenger side dash, you will see a cover that needs to be removed, 1 screw(LH side of the cover and a clip at the back hold it in place). Once off you will see a bunch of wires and a connector. This connector plugs into the resistor. There is also an actuator that you will need to remove. The bolts are tricky to get at. Remove the bolts and actuator pipe and you can get at the resistor bolts which will allow you to pull the resistor from the housing.

ITS THE SPEED RESISTENS THAT HAS BURNED,THE FAN HAS ONLY ONE SPEED , AND THE RESISTENS LOWER THE SPEED IN STEPS , GET A NEW ONE AND IT SHOULD WORK

Heayer doesn't work


The resistors provide resistance in the circuit, dropping voltage to the blower motor to slow the motor speed down. On high, the blower receives full voltage through the blower relay.

If you had High but no other speeds, then the resistor pack is usually the culprit. If you have all other speeds but high, the most common problem is going to be the blower motor itself, relay, or the switch panel.

You can check this by turning the fan speed to "high", unplug the blower motor, and check to see that you have roughly at least 12v at the plug. If you have 12v, that means the switch panel is activating the relay and the relay is working. Over time, heat kills the magnetic properties of the magnets inside an electrical motor. Without enough magnetic energy, you may not get enough opposing force to spin the rotor full speed when the windings energize, but still enough to spin at lower speeds.

Another thing you can check is the connector at the blower motor and the switch panel. Sometimes these will heat up, start to deform, and cause a bad connection. The bad connection may be able to handle the lower current draw on low speeds, but the higher resistance from the bad connection won't be able to handle the higher current while in the full speed position.

Hope this helps, keep me posted. be glad to help you get your heater working again soon.

A/C and Heater Only works on the highest speed


The blower motor resister is bad...It is very common in chevy trucks. The resister is located behind the glove box and is held in place by two screws, it will also have a wire harness attached to it. If you want to see a picture of it go to www.partsamerica.com and search for the blower motor resister.
