I just fixed mine. same problem, no ac light no fan. inside the heater control assembly there is a electric wiper arm on the fan switch. This arm connects all power for fan and ac. Mine broke out of the fan control switch. Dash is not too much problem to get out. Have to pull top dash center section out by puching forward and lifting out. pull all screws on center dash counsel. remove radio, two side covers that hide screwsand lower trim that holds emergency flasher switch. remove cables from heater control and wires and remove. Took me about an hour. The code on radio will need to be reset so make sure you have that handy. Hope this helps..

When in my 2001 town and country my front Ac will blow but not strong. If i an sitting still theres nothing blowing.Any answers would be appreciated thanks


This is because your blower fans aren't operating. As you're moving forwards, you feel the air going through the vents from the outside, as you may have outside air turned on. Switch to recirculating mode and see if you get the same results. Check the fuse for your AC fan blowers.

How do you check/ pull the control switch to a heater/ac blower motor on a 2010 Dodge Caliber? I have already replaced the resister.


The failure rate on the controller is rare. If you replaced the resistor and still no fan operation, try supplying direct power and ground to the blower motor terminals to see if the fan operates. If no operation, suspect a bad fan. You can also try slapping the bottom of the fan motor with the fan turned on. Sometimes this will excite the motor and make it work again if in fact the fan is an issue.

1993 Ford Escort Blower Motor & AC Switch


I'm going to start from the beginning.
The blower motor gets power from the high blower relay and it is grounded thru the fan switch and the resistor. So you should have power on the pink white blower wire coming from the high relay to the blower motor. The orange black wire from the motor is ground going to the resistor and fan switch. The blue wires on the control panel are for the ac compressor.
The high blower relay gets power from fuse number 5 in the box. The blower motor is grounded thru the resistor and then thru the fan switch.

After i change thebrake switch will my fan blower for my heater and ac start working agian


No it won't.The brake switch is for brake light,interlock shift solenoids,transmission TCC controls,and stoping the vehicle, You fan blower has a completely different power supply that is independant from the brake electrical system, For you fan blower to operate its either the fan resistor blower or the fans control switch to the fuse

I turned on the ac and the light does not work, the vents are not blowing and the car is running hot. I have a saturn SL 1996


First check the 15 amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under a cover. If the fuse is good, then the problem may either be the HVAC blower switch (which is the fan blower selector switch), the fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components.

Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well (working) because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on. What the ac light switch does is provide the electrical path for the ac compressor clutch to come on through the ac control relay which is controlled by the car's PCM(computer) when you want ac, but the ac light switch still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path(negative) from the blower motor. So the blower motor has to work in order to provide a ground path for the fan blower selector switch to be functional. You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. You'll see it. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. Unclip the connector and with the ignition on and the fan blower switch moved to any one of the first 3 selections, check for voltage using a multimeter. The voltage will vary because there is a blower motor resistor. Voltage should be higher on setting 3 than 1. If you do have voltage at the blower motor connector, check for a faulty blower motor. The auto repair manual will tell you how to do it using jumper wires.

It's normal that your car is running hot because the radiator fan works in conjunction with your ac compressor. If the ac is on, the radiator fan will be on and therefore the engine coolant temperature will stay in it's normal operating range. If the ac is off, the radiator fan will stay off as well and the engine coolant temperature gauge will begin to rise and show pretty hot (especially at idle). It will do this up until a certain degree then the radiator fan should turn on thermostatically and stabilize the temperature. It's scary and I know what your saying because it does that to my car if my ac isn't on. Don't worry it won't overheat.

The ac quit working...no fan, no air. The 30amp


check the ac blower transistor under passenger side of dash behind the blower motor. on my 2003 compressor would not cut on , front blower only operated on high an blew hot air, rear blew on all speed but only hot air. $58.00 at dealer plus tax. 15 minute fix. there is a video on youtube that documents the process. just fixed today

Front ac blower fan only works on only


many vechicles have a relay that when defective does not allow low speed operation, (it usually controls the lo speed) check in the relay and fuse box, there may be two boxes one not as obvious

Ac blower motor


Check fuse supplying fan is not blown,
Check blower control switch is operating OK,
Check relay controlling fan is operating OK,
Check variable speed resistor pack is not faulty (the resistor pack is usually located in the blower ducting, in the blower airflow),
Check blower motor ground connection is not missing.

AC fan will not blow


check the vents under the dash, make sure the a/c vent doors are not jammed, check the blower fan underneath the dash too make sure its still operational, check the fuse for the blower motor, then last check your freon level.
