| RE: 95 C220 A/C vent on dash does not open, why? Hey Kene, I have the same problem with my 94 C-220, What I do is that I leave it on 68 69 or 70 degrees and after a few minutes it switches from the defrost to the center vents, I have no idea how to fix the problem yet, I will keep checking to see if anyone knows how to fix this. |
