Are you saying u can't change the air temperature? do the blower speeds work ok? can u change the locations the air comes from, i.e. dash registers, defrost, floor?

    You need to replace the blower motor resistor, it is located near the blower motor.

Blows cold air


Did you buy a used climate control unit? Sounds as if it may be bad.

Tip

Climate control settings,on all vehicles


When using the ac on a hot summer day,or a mild spring day,the compressor runs all the time.If you set it to low,and turn the temp to cold or toward the warmer side,lets say cool,then the ac compressor runs also,it just cycles,on,and off.No matter what setting you are using on your ac control,the ac compressor stays on,using fuel.Get the most out of your ac,while it uses your fuel,to keep you comfortable.All vehicles have a MAX setting,or a recirculate setting.Always use this setting.I say,always use this setting,not only that,but use this setting.I stress this because you are pulling in air ,from the out side,that is warming the evaporator,and making the ac work harder to give you comfort.In the hot ,hot summer,the settings MAX,and recirculate,keep the air that is in the vehicle,in the vehicle.It recirculates the air,instead of bringing hot air inside the vehicle ,and bringing the temp,up,to a warmer temp.A lot of people don`t even know that this is on the control,or don`t know what it is for.Some times the recirculate button,or dial,will have a picture that looks like a C,but squared off at the corners.So folks,get more out of your vehicles cooling and heat system.Yes ,this will work on heat also,maybe not defrost,but on some cars,it will work.

Here can i locate the heat in a 87 voyger


Hi Kutis, Could you give us more information? I believe your referring to the cabin climate heat control. What belt did 'they' change? if was the belt for the AC? If it was I believe you may have the Air Conditioning running on cooling instead of heating? Look at the dash climate controls and you will see one for the AC control. If it is illuminated press the button to disengage it and the heat should work. If it was a different belt we need to know which one was replaced? We also need to know what else was done?

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

How do I turn on my air conditioning on my 2005 caravan. I do not have an owners manual. Thank you.


Looking at your climate control panel, you should see a square button on the upper right section with a snowflake symbol on it.

Depressing this button should cause an amber LED to light when the blower fan is on, and activate the AC compressor.

You will also activate the compressor when you select defrost with the mode knob.

Driver side air conditioning will not cool


are you not getting any air or hot air???
Here is a laundry list from my memory as to what may be causing causing the problem.
1. Low freon:car will act like this when it needs a freon recharge. Such did not solve my problem, however.
2. Stuck door. There is supposedly a "door" (for want of a better term) inside the heating/cooling system that regulates temperature and/or cabin airflow. The door opens and closes according to the temperature and and dual climate settings selected. If this door gets stuck, it causes hot to blow out drivers side and cool on the passenger side.
3. temperature sensor improperly reset. if the battery gets disconnected and reconnected improperly, it will cause a malfunction in the sensor responible for delivering the proper temp through the a/c system. Disconnect the battery and reconnect with negative terminal first; check all fuses that reference climate control, a/c , heater, etc in manual, remove for 15 seconds, reinsert or replace if necessary.
4. Computer malfunction. The problem may stem from the climate control interface itself (i.e. the thing with all of the temperature knobs and buttons). Replacing this is supposed to fix the problem.

BEFORE TRYING ANY PROCEDURE PLEASE CHECK THE RESPECTIVE PART

The car keeps coming up a code 23 on a 1999 chrysler 300 for the


Code 23= Blend door feedback control


On cars with automatic climate control: To enter diagnostic mode, set the temperature to 75F, press the the off button. Press Floor, Defrost\Floor, Front Defrost simutaneously for 3 seconds until the temperature display begins to flash.
On cars without automatic climate control, set the blower to any speed, turn the temperature control in between warm and cold. Press Floor, Defrost\Floor, and Front Defrost. All codes will flash via the Front Defrost button.
When the test is over all fault codes will be displayed (on cars without automatic climate control, they will be blinked out on the Front Defrost button).
