Vaccuum Flaps--Where do I check them? W201 190E

Where is the central location of the vaccuum lines for the heating/cooling bleand air flaps in a '91 W201 190E 2.6.

I have the central vents, passenger vent, and glovebox out but don't know where I can access the vaccuum flaps to test them with the mighty vac.

I have constant heat out of all vents, especially during acceleration. Already replaced the monovalve which didn't fix anything.

Any help please!

Unless I'm overlooking something here (no litature at home so I might be wrong) the switchover valve are under the r/h vent kinda buried under the aspirator motor. I'm believe the later 201 still has a heater comtrol valve in the cowl which is vacum controlled and they leak.
