Air Conditioning problem
1994 Mercedes Benz 320e Two Wheel Drive Automatic 177500 miles
Middle vents blow cool air, not cold. Driver and passenger vents blow hot air, and defroster blows hot air when air conditioner turned on

Anytime the A/C system starts blowing warmer air out, the first thing to check is the freon level. If the freon is low, recharge it appropriately. Remember, freon should NEVER leak. If you are having to recharge the system then there must be a leak somewhere. You should have a local HVAC tech locate and repair the leak.
