190e climate control problem/removal

[orangedawg]

I have a 1986 190e. I've got some problem with my climate control. First, it only blows hot air. I can adjust the temperature wheel all I want and only get hot air. I get air coming out of the top and sides of the dash that is hot. There is air coming out of the center of the dash but it is always cold. Also, the ac compressor only comes on when I select the max ac button, but not the normal ac button. I do have vacuum coming to the module behind the glove box.

So, unless anyone has ideas on what the problem is, I thought it might be the climate control. My question is how to remove it. Is there an easy way, or does the entire dash need to come out.? Thanks so much for any advice!!
