I just had a new A/C compressor and drier installed. Unfortunately, cold air is only blowing from the 2 outside vents. Nothing comes out of the 2 vents in the middle of the dash (hot or cold). Any ideas? Thanks.

THERE IS A LARGE VACUUM DIAPHRAM ACTUATOR THAT OPENS/CLOSES A FLAP FOR THE CENTER AIR VENTS ,
REMOVE THE GLOVEBOX AND LOOK UP HIGH IN THE CENTER OF THE DASH FOR THE VACUUM ACTUATOR AND TEST IT FOR LEAKS WITH A VACUUM PUMP , AND TEST FOR VACUUM SUPPLIED TO THE ACTUATOR DURING COLD SETTINGS.

ADDITIONAL VACUUM CONTROLS AND ELECTRONIC CONTROL OF THE VACUUM SWITCHES.

ORDER A COPY OR THE 2-CD MERCEDES-BENZ w123 REPAIR MANUAL FROM MANY SOURCES, IT CONTAINS ALL THIS INFORMATION .

Hi All;

I got my Mercedes CD off of ebay for less than $20, for a 2 CD set...

Make sure your order the one for your computer operating system, Win 98, XP home, etc...

Not as good as the old manuals but it will get you thru the hard times...

Good luck...
