Question about 2006 Dodge Charger

1 Answer

Temperature Control stays hot

After I use my heater and try to turn the air temperature back to cool, it continues to blow hot air. Most times turning on the A/C switch seems to get cool air blowing again, but takes awhile. What should I check?

Check the control module that controls the coolant flow through the heater core.

SOURCE: The heater is blowing cold but the engine temperature reads high

Hi
I would first check to see if both heater hoses are hot to the heater.
if 1 is hot and 1 is cold the heater control valve is closed or the heater core is plugged.

if you are sure that your heater core is not restricted. then try to recalibrate the climate control panel. if your a/c system is not working then DO NOT ATTEMPT THE RECALIBRATION it will make your lights on climate control panel flash codes forever.
to reclaibrate the climate control panel just have the engine running. turn the mode to vent, the temp to cold, the blower on high, then press and hold the rear wiper wash and wiper buttons at the same time until the panel lights up then wait about 2 minutes for it to run completly when completed. turn off ignition and then restart the engine try to se if you have heat again. if it doesntwork post the codes it gives you after the calibration test.

NO, PROBLEMS ARE NOT RELATED SEAT MODULE NEEDS TO BE PROGRAMMED AT CHEVY DEALER TO FIX ISSUE. IF YOU HAVE AN AUTOMATIC HVAC CONTROL UNIT WHEN YOU REPLACE THAT YOU WILL ALSO HAVE TO HAVE THAT REPROGRAMMED WITH THE LATEST UPDATES. BUT THERE ARE ALSO A LOT OF PROBLEMS WITH THE ACTUATORS THAT CONTROL THE MODE AND TEMP DOORS. THE ONLY POSSIBLE WAY TO DIAGNOSE THE PROBLEM CORRECTLY IS WITH A GM SCAN TOOL. GOOD LUCK

Why doesn't my 2001 Ford Taurus have heat but the blower motor works but only blows cold air.


Is the coolant level full ? Are the heater hoses hot to the touch ? Do you know where the heater hoses are ? Out in the engine compartment going through the fire wall into the passenger compartment . 2 hoses , one carries hot coolant into the heater core the other is a return back to the cooling system . If hoses are hot you have a temp. door not working . When warmed up what does temp gauge show ?
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the manual A/C-heater system is determined by the position of the temperature control knob (between COOL and WARM).
  • This control knob is connected to a potentiometer mounted in the integrated control panel. This potentiometer is electrically connected to the A/C electronic blend door actuator that operates the A/C air temperature control door.
  • The A/C electronic blend door actuator contains a reversible electric motor, another potentiometer and a printed circuit board. The wiper of the potentiometer is connected to the actuator output shaft and moves with the output shaft to indicate the position of the A/C air temperature control door.
  • Battery voltage is applied to the ends of each potentiometer. The voltage available at each wiper indicates the position of the potentiometer. The printed circuit board drives the actuator in whichever direction is necessary to make the actuator wiper voltage agree with the control wiper voltage.
System uses a reheat method to provide conditioned air to passenger compartment.
  • All airflow from the blower motor (18527) passes through the A/C evaporator housing where it can be cooled and dehumidified.
  • Temperature is then regulated by reheating a portion of the cooled dry air and blending it with the remaining cool air to the desired temperature.
  • Temperature blending is varied by the A/C air temperature control door which regulates the amount of cooled air that flows through and around the heater core (18476), where it is mixed and distributed.

My 2001 toyota tundra heater wont blow hot air. I checked to see if the heater core is cloged it seems fine the heater control valve is operating properly, and I changed the thermastat. and yet the heater...


If you've changed the coolant recently, it could be air locked in the heater core. To remove park the truck with the front higher than the back and remove the radiator cap. Start the engine and let it run while watching for a big air bubble burp coming out the radiator neck. Top off the coolant and continue.

MY 1998 FOR TARUS HEATER WILL NOT WORK.WAS DRIVING


It is most probably the problem with blend door or blend door actuator. But just in case I would suggest to follow the entire procedure:

First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is warm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest flushing the heater core.

My heater stoped blowing hot air.antifreeze level


If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,

Heater temp on mercury '98 mountaineer only blows hot


Everything that is heat and cooling in a vehicle is controlled by vacuum from the engine. It appears to me that your blend door vacuum line to the temp control switch is either off or cracked/broken and not making things work the way you want/expect. It's the vacuum friend.

My a/c won't blow cold and heater doesnt get hot


Is the heater working? Turn the A.C. off with the car at an idle. Turn the A.C. on and listen for the compressor to turn on. (should hear a click under the hood and the motor should change pitch. If no noise, the compressor is not comming on. The o-rings were bad about leaking on these cars, letting out all the freeon. If there is no freeon, the low pressure switch won't let the compressor run.

A/c blow hot air 03 jag s type R


You have 2 zone temperature control control. The heater control valve has failed and is open allowing the passenger side heater core to stay hot.
It is a very common problem and expensive to repair. It tends to be an intermittent problem and sometimes will work properly.
