Appreciate your knowledge and your help. As stated, I am trying to find a reputable mechanic in the area. Will let you know how it turns out.
P.S. Just bought a Climate control servo from Parts Shop (ouch !!!!). I know that this was the culprit since you had to bang on the old one to get it to work. Working on Mercedes might be fun but it sure isn't cheap!
