[DML] A/C Mode Switch Blues

[mike <cambpd@xxxxxxxxx>]

Last year I rebuilt my A/C Mode Switch to try and
correct the problem of very little air coming out of
the dash vents, and hissing from the A/C Mode Switch
vent position. I reinstalled the switch with (unlike
the way I found it) all the vacuum hoses connected and
to the correct positions.  

What I ended up with was absolutely no air coming out
of the dash vents with the fan on high speed, and now
constant hissing from both the vent and heater/floor
positions. I even disconnected the vent door linkage
to keep the door permanently open! But the only air I
have coming out is from the floor vents.  

To keep from melting this summer, I am considering
stuffing the floor vents with rags to try and direct
at least some air to the dash vents!!  

Why would hooking up the hoses to the A/C Mode Switch
cause constant hissing and no air from the dash
vents??
Because of this, I am sure that all the actuators are 
not working.

Would appreciate any advice!  Thanks.
