> Depending on the tempertures and pressures that can be normal. >> Every 6 seconds? That seems too frequent - is it? Thanks, Dave. Problem fixed, my D gets comfortably cold now. Took it to the guys at BrakeMasters who've worked on my cars for years and are always great to me. For a chain, this one particular store knows me and loves when I roll in driving something that isn't in their database ;) The problem, as I suspected from the 6-second cycle of the compressor, was that there was almost no refrigerant. Where it went, I have no clue because there don't seem to be any leaks. They tightened this and tweaked that and I get a 40 degree drop with R12. The other problem was that when EuroSvc charged it last year "they didn't vacuum out the moisture so the system wouldn't get cool enough." I'm just quoting all this since I admit I know absolutely nothing about auto A/C. I've never cared if my A/C worked or not, but in this little low-to-the-ground car with limited windows it suddenly seems important for a desert summer. By the time EuroSvc got to my A/C they were pretty fed up with working on the D. They crank out Mercedes for a tidy profit but having to go to school on the D was more of a burden than a pleasure for them I think. .........................LP 10440 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
