Sorry Larry, I missunderstood. Yeah, it's working, and yeah, almost anything would be better than taking the dash apart again....

I would pull the glove box and check the vac servos for leaks. I had to replace all the right angle connectors on my switchover valve, none of them would hold vac on the valve after R&R. Cheap fix, eh?

You won't be able to see the flaps, but you will hear them move.

Sounds as if your full recirc is not working -- but this could be due to cooler outside air. I would expect vent temp to stay pretty much the same, though.

A clogged expansion valve will result in very low low side pressure, sometimes (depending on charge and outside temp) a high side pressure too high. If completely plugged, you can blow a high side hose in hot weather (I know, I did, but not on a Benz).
