Air Conditioning problem
1990 Other Mercedes Benz Models 6 cyl Two Wheel Drive Automatic 247500 miles
I have a 1990 300E with 247,500 miles. The heat and air quit working so I replaced the blower motor first (didn't fix problem) then I replaced the regulator. The air worked for about 3 minutes then the heat came on and I couldn't adjust the fan speed. So then I replaced the climate control unit with a brand new unit from mercedes (I intend to keep the car for a long time). Nothing at all works with the new unit installed but when I reinstall the old unit I get about 3 minutes of air then heat again. I've checked all the fuses. Any ideas, I'd appreciate any help. Thanks.
