Again I am not a mechanic or AC expert but your comment makes sense because the temp did not change when I adjusted the dial. Is this monovalve vacuum controlled cause the vents did not change either when I pushed the defrost button.

Now, Hip001, we all understand that you are not an AC expert, but I know you do not have a 1985 300SDL.
Your typo is forgiven.
The monovalve "rebuild" kit is easy to replace. I did it. If you are standing on the passenger side of your car next to the battery, the monovalve is toward the driver's side looking over the battery. If memory serves me correctly, you don't have to remove the entire valve (it's a boxy kind of looking thing with 2 rubber coolent hoses and an electrical connection). You can unplug the electrical connection and take the 2 screws (do NOT drop) out of the top. The thing "pops" open (is there a spring in there? I don't remember). Inspect the diaphram on the top of the brass looking shaft --- It probably has a tear in it. Coda's did.
Anyway. Remember how the thing fits together. Take the thing apart with all the parts lined up. I think the rebuild kit comes with a shaft and new diapharm on it. Put all the parts back together.
