1985 380SE - this is the rear vent behind the center console (under the armrest) that blows at the rear seat passengers. I can't get any air to blow out of mine. I think it would really help circulate A/C through the passenger compartment if it was working.

I've done a search but the info is vague. It appears the vent lever *might* control some sort of A/C flap behind the radio that controls airflow to the vent. How do I trace this cable, and where is the flap that it controls? Can I just wedge the flap open so the rear passengers get A/C?

Also, some posts seem to indicate that the vent only blows heated air. Other posts say fresh (vent) air only. I need A/C air to blow out of there. Is this possible?

TIA!!!
