I have the same problemwith my 2003
did you resolve your's?
On the vacuum diagram there is a vacuum resevoir and a check valve, maybe the check valve is plugged
i dont know where in the vehicle it is located tho, do you?

Yes I did solve the issue with the heater controls
in the back of the engine compartment on the left sibe in the back-behind the intake manifold plenum there was a small red vacume hose. It plugs into the upper intale manifold and then connects to a t where a black vac hose goes into the firewallthe res hose was cracked right off I got a small peice of rubber hose and some tape and I patched them back together and then like magic the selector switch worked and is still working
