2001 ford crown vic heater/ac fan switch doesn't blow anything at all on all speeds


you need to replace the blower resistor...90 percent of the time that will be the problem in your situation...before replacing it..check for power to blower motor first...if it has power then replace blower motor if not its the resistor

Heater blower motor.,Highspeed only works..problem??


9 out of 10 times its the heater fan resistor doing this. it has wires that corresponed to diffreent speed settings for heater fan. the resistor is beside the blower motor, Your Kia Sportage Blower Motor Resistor controls the heating equipment in the vehicle by opening and closing the fan motor. The Kia Sportage Blower Motor Resistor allows the heating and climate control system to control the speed of the vehicle's cooling fan. its under the passenger side glove box. undo 2 screws and disconnect the electrical connector. thats it!!

My 2005 gmc yukon rear a/c or heat blower will not come on front a/c and heat work well


{: ) If the front a/c and heater is working fine, that's good. At least the problem can be isolated on the rear HVAC circuits only.
Check first the RR HVAC fuse 30amp at the underhood fuseblock and the IGN 3 fuse 10amp at the IP fuseblock. If you found them good, then you can begin diagnosing the blower circuits wirings and connectors.
A faulty blower definitely will not give any output. If it doesn't spin for some reason, rear a/c or heating cannot be circulated.
A faulty blower resistor or speed control processor can also cause a zero air output. Sometimes, the blower may only work at certain speeds only.
A faulty rear HVAC control switch may not give the proper signals to the blower resistor or speed controller, and in turn will render the blower motor disabled.
Sometimes it can be a terminal connector being loose or burnt. However, the most usual cause for this type of problem is a faulty blower resistor.

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.

I have a 2006 yukon, when I turn the heat to 90 I get heat, when I move it to 89 cool air starts coming out. My mechanic said that when it is on 90 it is going full bore and when I move it to 89 the air...


on the heater vent from the left side you will see a switch ture your heat on then watch the switch when you move the control to 89 see if it moves

89 Chrysler New Yorker , heater/blower came on while driving, can't turn it off. The buttons don't work.


Try a new heater blower motor resister, most likely shorted out, the resister controls blower speeds, and also makes blower run.
