First check the fuses, all the fuses it maybe hook to something else always check them all. If OK check to see if you have power to the blower motor by unconnected the plug-in and hooking a test light to a good ground on the car and putting on each terminal of the lead going to the motor when the key is on. one of them should turn the light on. if it does then your going to need a blower motor most likely.

My heater quit working but makes a sound like it's trying to blow. What could be my problem?


the heater works from hot coolant flowing through it so if it stopped working but was working recently , the problem will be in the heater control tap not turning on ( control module )
the blower works of electrical and trying to blow air indicates a problem in the fan speed control ( again a control module module)
if you have a climate control system in the car It may be the climate control module that is faulty as it controls both

2001 Jeep Grand Cherokee Heater


the heater core is removable from the climate control unit. The climate contriol unit has to be removed to replace it. The A/C system must be evacuated and lines removed as well as the dash, to access the climate control unit. The steam is coming from a leaking heater core.

Why wont my a/c or heater fan come on?


When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

The heater fan on my 2006 GMC Sierra only blows to defrost. Directional control switch doesn't change it.


Most likely is your blend door is faulty (bad motor/broken tab?).
Defrost is the idle possition ( as it is the most important).
You may have a disconnected vacuum hose from the climate controle panel if you recently (ever?) had work done in the dash area...
But my suspicion is the blend door motor...

Fan control knob on a/c and heater will only run on high speed. 2003 dodge mini van


I replaced the fan module under the glovebox on my 2005 Town & Country last night. Mine would not shut off at all with key on. It only blew on high no matter where I set the switch. Mine also had the climate control which makes a difference. If it is not the auto climate control it is usually the blower resistor if the other fan speed selections don't blow at all except on high.

Your closing in. There is a motor that will open the heater core venting to allow it to blow into the car. Get a heater core install picture from your auto parts dealer or car dealer for specs of where and how it is driven.

Heater fan will not work until the car warms up and then it will start to work.


If your van has climate control try switching from auto to manual, a lot of auto climate controls "Wait for warm up" before turning on fan for heater.

Passenger side blows hot air when front control set to Air


you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.
