This is a new one for my 190E. Driiving along with the ac on..thumbwheel rotated to "min" everything is fine and then all of a sudden....no ac! Turn off the ac button...set to vent and it blows air (that rules out the blower motor I guess). Wait a couple of minutes...hit the ac button and all is well again. I did notice that the air didn't seem to be quite as cold as before. FYI- Just (last week) had a new condensor-fan clutch-dryer installed....and re-charged with freon. Anybody had a similar problem? Since I'm driving from Tucson over to California having my ac working is a big deal!
