0linc ls v8 added freon compressor came on but no cool air doing good the day before now blowing hot air out all vent's


If the AC was working good the day before, why on earth did you add freon? Did you use a real manifold set or just the plastic "add a can" parts store stuff?

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.

My air conditioner works but does not cool . i have added freon the last two years and fixed the problem ,did the same thing this year but did not help .


When self adding freon after it leaks out you get air trapped in the system. After adding freon a couple of times the air expands not leaving room for the needed freon. To continue adding freon with air tapped will knock the compressor out pretty quickly, there's not enough room for both & the air is keeping the freon from being able to cool properly give the false indication of being low on freon. The freon you are adding has the dye added to assist in finding the leak since freon does not evaporate nor dissipate it its being leaked out. A black light will assist locating the leak. The best thing is to have the unit checked & serviced by a mechanic...he'll charge about $ 150.00 to check for leaks, remove the old freon...his machine will tell him how much air its trapped in the system by how little freon is removed. For the service fee he will replace valves & gaskets, where needed, correcting most leaks. After sucking the system down & recharging the problem should be corrected.

Added freon to ac and car will not cool


Needs to be checked for a freon leak, best way to do this is to recharge and add dye, with a uv light you will be able to fine the leak, most auto parts sell the dye, and the flash light you will need to fine the leak, good luck.

Recently added a leak stop r-134a freon to my 1996 deville and after about 2 days the compressor wont turn on and it wont go to "auto" cool and stays on "econ" cool. after adding freon to car i noticed it...


If it's misting, this is a definite indication of an overfill. You should get a hose with pressure guage on it to avoid this. In the meantime, if a dangerous condition exists within your compressor. The optimal amount of pressure you're looking for is in the 40-45 psi range. Definitely needs attention or you will do damage to the system. Best of luck.

If Freon was "added", the system may have moisture in it and that causes blockage of the expansion valveand makes the soamolies hijack oil tankers. Just kidding. Figured this would be all foreign to you anyway, no offence.
Ok, Adding freon is not really a good fix. The system should be evacuated with a vacuum pump to remove any moisture in the system which will freeze and block the expansion valve, Hence, no cooling.Having the signs of this problem already should have called for evacuation. Adding freon from a kit increases the possibility of introducing more moisture into the system. You will need to have it properly service at this point. The drier will also let go of any moistue it has trapped when evacuated for 30 minutes @ 29 in. of vacuum - good luck
