Sounds like your temp door might be broken or the motor that moves it might be bad,its behind the glove box,pull the glove box down and turn the temp knob and take a look at the motor and see if it is turning,if it is, you need to have the temp door replaced,hope this helps

My 2007 grand marqis only blows hot air from the defroster vents. will not blow any cold air. Need help before spending a lot of money taking out the dash.


If you have electronic automatic temperature control, press and hold off and floor buttons at the same time, with key in the on position, then release and press auto for 1 second.this will put system into self test. If numbers come up,152-52-32- 132-or some code, Google it..most likely the blend door actuator,some have found a way to do it without removing dash at s much lower cost.

1995 Buick Century blowing hot air.


A mechanic would check the system with a set of pressure gauges. If the compressor is running, the low side would read around 30psi and the high side would be around 250psi. That is how you know if the system is full of freon or not.
You may have to get a professional diagnosis to proceed. If you replace the compressor, the accumulator needs to be replaced and a vac pump is used to pull all of the air out before the freon is added.

When I turn on my air conditioner in my 2004 Chrysler Sebring 2.7L it blows cold air until the car has been running for 10 plus minutes and then air blows hot and the RPMs go up and down drastically.


A mechanic would check for voltage at the ac compressor and the freon charge when the ac stops working.
If the compressor is cutting on and off the idle speed will change.

Ac on 96 grand marquis continues to blow hot air with new compressor and freon?


The first question is do you know if the ac compressor is running ?
If one ac line is hot and the other is cold you may have a blend door problem under the dash.

2004 camry ac light blinking and throws hot air. Suggestions?


My 2003 Toyota Camry AC often starts blowing hot air and the AC light starts blinking. I don't know why the following process works, but it does. Using the temp selector (left) reduce the temperature all the way down to Max Cold and then push the Auto button. It will start blowing out very cold air. After a little while push the temp selector to the desired temperature.

2001 S60 Air blowing hot


There may be a problem with the AC compressor pressure cycling switch, it turns the AC compressor on and off as required to maintain proper pressure in the system, it is located in the low side line (large AC line) under the hood, it will have 2 or 3 wires going to it.
