On my recently purchased 1991 190E 2.6, I've been trying to figure out these problems with the climate control:

(1) The heat doesn't seem to work at all. It doesn't matter which vent selection I choose, only cold air comes out. The auxiliary water pump seems to be working, not sure how I would check if the heater core is working.Any other ideas as to what I can check?

(2) The blower motor works well, but i've only been able to get air to come out of the center vents. Nothing comes out of the floor vents or dash vents. I've read somewhere this could be a "blend air door" or possibly a vacuum line... any ideas?

Thanks for the help.

I am experiencing similar problems although my defrost words. Here is a white page on the 190e climate control that may help with your search.
