Hi,
Everything seems to be working well heating-wise with my 85 300D's ACC except that the leg flaps just won't open up. According to my Mercedes shop manual on CD, I should be checking out the proper switchover valve among the horizontal row of 5 switchover valves that are somewhere in the car. Problem is I just can't find them. Any clues to where to find them would be most appreciated, as would any other hints in solving this problem.

Thank you,
Dan
