Hello, after the search function could not answer my question I simply ask the question here. In my 850er BJ94 MJ95 comes from the middle vents only cold air. If I close both, it mixes with the warm air on the outsides (the air flow outside becomes cooler). Does someone know the problem and can give me a hint, what I should look at first. In addition, a squeaking out of the right vent comes. To the grid only the ventilation tube goes. Where exactly the blower is located to oil something there? Achso the car has the climate automatic, if that serves the analysis. So far… Thank you Janko
