Does anyone know what the diverter flap is used for? I pulled my glovebox today, and tested all the vacuum pods - this one and the recirc small lift are bad.

Symptoms are no air through center vents (center vent pod holds vacuum, but I can't hear any flap actuation), and low air volume - high blower sounds like high blower, but only puts out min blower air.

When I applied vacuum to the diverter pod, it wouldn't hold a vacuum unless I quickly applied more than 10" Hg, then it held, but slowly leaked. With the engine/fan on, I got lots of air through the center vents, but little through the side vents.

any ideas?

p.s. Thanks for an excellent post, I've referred to it often enough that it gets bookmarked..!
