MY AC WAS BLOWING JUST COOL AIR (HARDLY EVEN COOL) LAST YEAR...MECHANIC CHECKED FOR FREON LEAKS ABOUT 3 TIMES AND NEVER COULD FIND A LEAK...THE A/C WOULD COOL AGAIN ONCE THEY TOPPED OFF THE FREON...THEY SAID I NEEDED A NEW COMPRESSOR AND HEATER HOSE SO I REPLACED THOSE...NOW A YEAR LATER, THE CAR IS STARTING TO DO THE SAME THING...JUST BLOWING AIR...NOT COLD AT ALL...DOES ANYONE HAVE ANY IDEA WHAT THIS MIGHT BE CAUSED FROM...I THINK IT MAY HAVE NEVER BEEN MY COMPRESSOR....

 

U already know what the prob is now U simply need to find the leak.
Did the stooge put dye into the system?

 

They did use die, but never found any sign of the die so never could prove a leak so i guess they assumed it was the compressor...only they said it could be...right!!!!!!

 

freons natural state is a gas if threre was not a leak it would still be in the system u have a leak if they haft to keep adding freon in U or they will need to find a leak and not throw parts at it. There are UV lights sniffers all sorta stuff to help the inexperienced to find a leak. I would say U have a an evap core leak that is what I see most often on a 2000 300
if the leak is not outside its inside simple as that.
