97 Plymouth Breeze won't blow cold air due to freon leak.


Your AC system is a closed system, so the fact you have to put more Freon in, means there is definitely a leak. I would check it out with a mechanic.

On a 2001 chevy silverado 2500HD the ac blows cool in idle or slow speeds but while driving the air gets warm and then cool warm and then cool etc. i cant tell if the compressor is cutting on and off


You might be low on freon if not compressor going bad to see if your compressor is going on and off turn on a/c on max have some one hold gas peddle down around 1500 rpm or just at a small fast idleif compressor goes on and off recharge it most likely one or two cans will be enough

Air conditioner stopped blowing cool air. Added freon. Worked well for a few days. Now only blows cool air on passenger side.


Chances are you have a pretty fast freon leak, and the passenger side will be blowing warm within a few days. I have the same thing happen on a couple of my GM cars, except my leak is very slow; warm driver's side, cold passenger side.

You can try and top off the freon again, but I suspect you're going to have to take it to a shop to find the leak and get it fixed. Plan on spending some big dollars for the repair.

Good Luck.

I have a 2004 2.7 6 chrysler sebring lxi. ac blows really cold and periodically just starts blowing warm air. is there a relay or temp. sensor that might be going out and through a malfunction shuts down...


Cooling fans working? If you notice the air getting warm mostly while stopped, probaby cooling fans not turning on. if the fans are working properly, may be low on freon and need a recharge.

AC blow out hot at low rpm


when you are stoped does the car idle fine. when the rpms are low the compressor does not get the pressure up high enough. you may need to get you idel turned up a little or your vaccume advance may have a vaccume leak.

A/C Gone Warm


U have a leak in the system, be it a very slow one. Have the systek leak tested with a black light, it comes from the factory with dye that glows under a black light leak detector.
