Hi Gang, Yesterday with the vent or A/C button pressed (Position #2 & #3) and temp wheel turned all the way down, air does blow out the center vents. Now I know from the ETM, it can either be the ACC unit or this other "unit" (for lack of a better name) that controls the vacuum to open/close the vents.
One question....on a W126 WHERE is this "unit" located, and what's the best way to access it for troubleshooting? Also, any any advice on troubleshooting/repair of this problem would be greatly appreciated! Thanks, Angelo Giaimo 1990 350 SDL 265K Miles ....Still Kickin...........
