I have a 96 300D. Power steering works fine down the road but becomes intermittent when you need it most, parking. Could be low fluid. I am not stupid, but I can't find where you check for that. Could it be a pump?

 

W124 81 300SD Turbo My A/C air output is stuck in an intermediate position. It does not go up or out the main vent in the dash. It does a little of both. I had a new controller (and new fan) installed but it did not help and the fan is always on low speed regardless of temp. It is also not as cold as it should be. I have it in a shop now but would like suggestions as the shop is not familar with the whole system.
