A/C compressor won't engage 260E
 

It was working about 2 months ago perfectly fine. I think I found the leak in the system to be the high side port....I have pressure in the system, but the compressor wont start.

I've switch Klimate Relay /w working one from my 300TE, so that rules it off.

I just checked and I have voltage at the pressure switch Ignition on, engine off. One terminal has 11.56v, the other terminal has 0.65v. Sound ok? When I bridge the terminals though nothing happens...

What else could be the problem?

Well checked pressure again and its leaked out again. Back to the drawing board...

Just gonna take it to someone to find where its leaking from. They have much better tools than I. Will report back where its leaking from for any tips.
