Turned AC on while idling and the AC seems to do fine at idle. I have to do a test drive to really prove this out.
My question is, when I press the AC switch, should the aux fan turn on immediately? And stay on as long as the AC switch is pressed?
Thanks

No, the aux. fan will only operate when needed either by the aux. fan temp switch, or the high pressure switch on the receiver/drier.
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
