You still have a vacuum leak(hose) or a bad vacuum motor on the vent selector -- usually when the vacuum leaks off the air will only come out the defrost vents -- tee a gauge into one of the lines so you can see what the reading is -- a hand pump would help in diagnosing the vacuum motors
" ice cold then slowly quits blowing out the vents"
Are you saying no air at all out any of the vents -- or air only out the defrost?
Cause that is a whole different problem

For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.
