I replaced the complete heater control unit and now it switches correctly as it should "BUT" everything is still coming thru the defroster ??? I checked for vacuum leaks but didn't see any apparent issues?
Anyone ever run into this ??

I have run into this. Behind the glove box is a series of vacume lines that intersect and connect in a "group" or "junction fitting" (for lack of better words). When I had that same exact problem it was because a line had pulled loose from this fitting. Once I plugged it in the problem was fixed.
