I just noticed that the ventilation fan on my (non-AC) 190E doesn't work when the slider switch is in speed I - speeds II, III and MAX work fine, soI assuming it's not a fuse problem
Can't really be a fuse problem. Bad dropping resistor? Bad switch contact? Getting sticky motor that just can't spin with that little juice applied? Could be any of the above. Step one is to see if the motor's getting juice on that setting. -- Jim
