I have a problem with no air coming through the cenents, the side vents or the
floor vents. I had the programmer replaced but this didn't solve the problem.
The mechanic said that it might be the vacuum servos in the heating unit.

The diagnostic (07) says that the cetner flaps should be open but no air is
coming through. Has anyone ever replaced these servos or had a problem with
them?

I was also low on freon (down 1.5 lbs). They spent quite a while looking for
leaks but couldn't find any. I guess we'll see if there is a leak this summer.
They thought it might be some contraction due to cold temperatures here.
