That fuse is the first thing I would have checked, maybe that was your problem having the wrong/defective white fuse. I purchased our '93 190E new and about a year ago I replace every fuse in the car with new ones.
Report back with your test results, you might have just saved yourself some unnecessary expenses.
Good luck

Interesting! Well, while idling my AC never got warm!! It stayed cool idling at a light and when I pulled over for about 5 to 7 minutes. It definitely was running colder while driving than idling, but not near enough to make it uncomfortable. In fact I could have sworn that while I was pulled over and idling it felt like the AC got a little colder! It could be my wishful thinking too! I expect a 4 cylinder at idle to not cool as well at speed, but is that normal?
Thanks!!!
