Hi all, my wife is complaining that she cannot completely shut off the
flow of cold air from the center dash vents in the car. I took the car
for a spin, used the airflow control to close it but it seems that there
is indeed an uninterrupted flow of cold air in from the middle dash
vents. This appears to occur independently of the selection of
re-circulate or any of the other air controls.

Is this a common issue? what is the fix?

I don't know if the 124 climate control is very similar to the 123
climate control system. But in my 300 TDT I had to remove the dash and
replace some failed vacuum actuators to repair that same sort of
problem.

Whoa that sounds nasty, and is a bit above my skill level / available
time.

I would first change out the yellow checkvalves by the brake master
cylinder... you may have two of them. These checkvalves are for the vacuum
controlled devices in our climate control system... make sure there is
vacuum there while engine is running.
