Exhaust Fumes in A/C
I have a 86 190e 2.3 and I am getting exhaust fumes in my A/C vents when I am at an Idle. At cruising speed this isnt a problem but at Idle the fumes a very strong and I have noticed this happens even when I sat at idle with not other cars around (obviously other vehicles arent the source of the fumes). Any help guys would be greatly appreciated....I would even be willing to send the people that help me figure this problem out a nice custom printed mercedes tshirt!!
