I have a 1999 c230 Kompressor and I have been searching for the past few days looking for a solution to my problem but haven't any luck. So I come to you.

Recently, my AC stopped blowing cold air. So I pulled out of my AC manifold/gauges to check the pressure. Sure enough it was low on refrigerant. I recharged the system and everything was working fine for the next month or so when it stopped blowing cold air again. I check the pressure and it was low so I figured there must be a leak. I charged it again and put some dye in there but I couldn't find the leak. Now even though I can hear the compressor turning on it still won't blow cold air. Then, just out of curiosity, I turned the temperature control to full heat and let it run for awhile but there was no change in air temperature.

Any ideas?

 

Correction: The heat does work. I was driving it around today and put it on max heat and no problems, still no cold air.

 

Are you saying you do get cold air but it will eventually blow hot due to a freon leak? Can you make sure there is freon in the system, raise the RPM and record the High & Low readings on the gauge... it is easily interpreted for newbies on google.

 

The AC system also run through your dash... The leak might be in ur dash....

Thats pureeeeee missions to fix.... You have to take the whole dash out.....
