Air conditioner does not work, will only blow hot air
My 2002 Mitsubishi Eclipse GS has problems with the air conditioner. I've had the freon level checked, and it was empty. However, once the freon was pumped back in, hot air still came out of the vents. I have had problems with the air conditioner before; a leak was discovered and a hose had to be replaced, I believe. Could this be an issue with a leak again or some sort of other problem, such as an issue with the air conditioner compressor? I would appreciate any advice as to what to look at next.
