Question 1997 S320 A/C Blowing Hot
I have a 1997 S320 that I changed the Water pump and some other items on the engine and now the A/C Blows hot.
This did not do this before the water pump went bad.
I have checked the A/C compressor and it is working and has the correct Freon in it.
I believe there is a problem with a vacuum causing the blend door to stay on hot.
I have checked the Vacuum line that runs from inside to the intake and it is good. I find no vacuum leaks anywhere.
My repair book shows very limited pictures on this issue

any help would be great.
