Searched the archives and found many problems with A/C. Mine is broken and I don't use it, so I didn't care. My problem is that during regular non-ac use the temperature wheel doesn't control the temperature. It's just blows super hot air with of course the exception when the car is warming up. It's winter now, and I have to have the window cracked open to cool the interior. Any known fixes? My car is a 86 190E 2.3-16. Thanks in advance.
