SOURCE: Heater fan control arm broken.

My 06 Dodge Stratus did this same thing after I had my transmission replaced. I thought the guys at the shop did it but come to find out the actuator that controls the knobs and the turning of the fans for heat and cool air had popped off of the turning mechanism. My uncle took out the glove box so he could access the back of the heater/ac panel. There should be a round mechanism that will spin back and forth when turning the knobs from cool to hot and 1-4 for wind speed control. On top of that know are small notches that hold a white, possibly grey "hook" style device that holds the turning mechanism in place once you change the settings from hot to cold or between 1-4 of the wind speed control. The "hook" style device may be stuck. Try prying the device off of the turning mechanism and getting it in to another one of the grooves on the mechanism. If you can get it to move you should be able to get it unjammed.

Hope this helps. If not, I have no idea.

My 1998 gmc jimmy slt has a heating problem. The heater wont turn off. As long as the car is on the heater is on full blast. The fans work and everything knob wise works but the heater is always on.


The air temperature valve electronic actuator positions the temperature door according to the temperature setting of the temperature control on the temperature control knob. For the full COLD temperature setting, the temperature control returns approximately 12 volts to the air temperature valve electric actuator. When the temperature setting is changed to full HOT, the temperature door is moved to the warm position and the output drops to about 0 volts. For a temperature setting in the mid range, the temperature door is positioned according to the voltage supplied through the temperature control switch.

2000 chevy silverado not blowing hot air


1: not enough liquid in the system (air in the heater core)
2: inoperative heater valve not allowing hot liquid into the core
3: hot/cold blend door in the heater box stuck on cold
4: clogged heater core
A clogged heater core will have one hot hose and one significantly cooler hose at the firewall connection; easily tested by hand. a good core will have both hoses very hot to the touch when the heater is on full blast.
Make sure that the system is full and at operating temperature, and the heater controls set on full heat. Feel the hoses at the firewall; if they are both too hot to touch then the problem is in the heater box or controls.

1992 honda accord radio and ac stopped working


Make sure your fan is working properly. When you turn on the heater you are forcing the fan to cool the radiator. It may not be turning on automatically when it is supposed to. Let us know if this helps..

There is a blender that controls the air flow to go through the heater core for heat, and the evaporator for AC. It very well could be stuck.

You maybe able to try and get it to get unstuck by running the cars AC and switching from heat to AC back and forth and see if it gets unstuck. Just turn it on full blast and go from heat to cool.

If that fails, then you may need to service it. There should be a Lever Marked VENT under the dash, usually by the Brake and other pedals on the Driver's Side. Close the VENT and that will stop the Air from coming in and leave the A/C Blowing through the outlets(Vents).

I also read this online if you have an electronic climate control. "On climate control press off and heat button and let go quickly. Then press automatic. The display will start rotating eventually displaying a code 025,125 , 024 etc. Then press defrost to stop. You may hear blend door operating atb that time. It worked for my climate control."

Sounds like a problem with the fan switch. If you can find the fuse for the blower motor, you could pull the fuse to stop the fan until you can get the problem fixed.

All i get from my heater is heat i cant turn the ac on, and when i turn off the heater it still blows hot air


Sounds like a stuck heater core valve. Find heater core valve. Under hood, find the two heater core hoses going into firewall. One of the hoses has a valve. Operate temperature control (full heat, then full cold) check that valve changes position. If not either replace valve or control system failure. Also, when temperature control in cold position, one hose should feel hot and the other cold. Temp fix: disable valve to close no heat or on heat.

Air Conditioner and Radio have amind of its own


Just a few steps that may lead you to finding a solution.

Check any fuses associated with the radio and ac, and replace them if need be (only a few bucks and auto parts stores).

Also the check the climate control, the unit may be defective.
