W204 Climate Control not very cold

Hi All,

Got a very strange problem with the air con on my C Class.

when I got it the ac had recently been recharged and worked fine, several weeks later it stopped blowing cold. Had it checked and it had way too much gas in it.

had it recovered out and regassed to the right amount, all worked fine and nice and cold, although not ice cold like my wife's 2012 B Class.

today, I got in the car and no chill at all for about 15 minutes then only slightly cool. Again had it checked and its still holding pressure no leaks. Compressor appears to click in and out when you switch off the ac with the engine running.

anyone got any ideas before I take it to an MB dealer and spend a fortune.

many Thanks
peter

Update, just popped into a shop, warm on the journey there, cold after a 5 minute stop. Must be electrical.

Are there any ac compressor relays? Can see anything in the book on it?
