This could be caused by two items first make sure your headlights are on durring te day and if the A/C works it is a open ground or the temp diff from day to night is just enough to change freon presure in the system to engage the A/C presure cut -off.To fix that simply add a little 134A freon!

Air conditioning system, when you turn on the air conditioner the drivers side blows cold air and the passengers side blows hot air? What causes this problem?


The most common cause of this is that you have a stuck air temperature control blend door, this can be a motor actuator issue or a jammed door or both (common). To replace both parts you will need to completely remove the dash from the car to access the blend door.

Heating and air


My first thought was low coolant, but with the added point about the ac I'm leaning toward a blend door problem under the dash.

A/c blowing hot air with low pressure


The first thing to do would be go to your local auto parts store and buy an air conditioning recharge kit. Provided your vehicle isn't too old, they sell recharge kits that require no tools.

If their is a leak anywhere while you recharge, you will know.

Try recharging the air conditioning first, it is very simple and the kits come with simple instructions.

If there are no leaks, your A\C will blow cold air again. As for the pressure, if it continues to slightly blow air you may be looking at a new air compressor unit or a vaccum line. A new unit will run you anywhere from $200-$2000 dollars plus labor depending on the vehicle.

If the recharge works, at least you will have slightly blowing cold air rather than hot and you can continue that way until the unit fails.

Air conditioning blows hot and cold air


You will need to know if the compressor is working when it blows hot air to proceed. It could be an electrical problem, a blend door problem, or the a/c clutch on the compressor.

The air conditioning system will only blow cold air. Regardless of the mode, I can only get cold air. Can you give me an idea on how to fix the problem? Thanks Don 615-653-3834 drcamp117@comcast.net


The air conditioning is supposed to blow only cold air. Are you trying to get the heater to blow hot air? Make sure the temperature selector is in the hot position.

Problem with air conditioning on 2001 mitsubishi mirage. "Sometimes" will not blow cold, just hot. Coolant level ok. Usually will will start blowing hot after runnning air while car is stopped at idle....


the air conditioning system has most likely drawn moisture this is not good take it to have the system recovered and a new restrictor valve put in. leak checked and recharged

Ford ka heater blows hot air all the time


Your problem is a faulty heater control valve. The design used on these vehicles allows for hot water to flow constantly and compete with the evaporator as there is no blender door. You have to replace the valve and possibly the control head. Meanwhile, you can bypass the valve to have cold air
