Hello, can't seem to find this issue addressed anywhere. I'm not getting any air out of the right side dash vent in any mode. Everything else seems to work normally. I've run the diagnostics on the control unit but don't see anything out of spec. Thinking it could be a failed vacuum element or a broken/disconnected vac line or even a malfunction in the Y11 distribution block.

How do I get to the Y11 block on my 1999 SL500? Seems like that would be the place to start, not sure.

Any input would be greatly appreciated!
