Hi guys
New to this but cant find a answer to my problem in threads. My AC (W203 180 comp 2006 mod) is not cooling all of a sudden looks like comp not running. checked all the fuses Gas press static is around 80PSI. the press switch under radiator test open circuit on all 3 pins(Is that right?)Tried to bridge the pins but no go. There was a funny sound (seems like a valve releasing pressure) around the comp side a couple of days ago for about 10 secs but AC was still working after that.
Please Help?

Your compressor is dead. Time to replace it.

Note that your car's AC compressor has an internal swash plate instead of a pulley-mounted clutch. You will not be able to visually see the compressor running. But, if you see no changes in pressure when you switch on the AC, then that does tell you it is not operating. You really need to get a scan of the ACC system to know for sure what is going on. You cannot use a generic OBDII scanner - you need SDS (MBZ's Star Diagnosis System, a.k.a Xentry) or something like the iCarsoft i980 or MBII, or the Autel MD802 Elite.

Yes u were right comp sized. Took it out (what a mission) opened it up saw the swachplate was stuck.
The car had a leak since i bought it and just filled it every time when gas was low. Think i should have put some oil in cause it looks like that was the problem. Bought a new comp and filter drier and going to put it in tomorrow. Goodnesss but genuine MB comp(Denso) is expensive R20518 .....got 1 from Diesel electric R4900
Thats for advice anyway guys
