I have an 84 533i that one (1) year ago I used a heater control valve replacement kit to replace the broken rubber diaphram. Now a year later when I turn the heater on and move the temperature control knob around other than turning it completely the the left, the heat is ALWAYS HOT! Can someone who has had the similar or same problem please help me out? I need to get this fixed ASAP so I'm not being "blow out of the car" with HOT AIR and frustrated!!

Sounds like the actual switch has gone South.

if the valve gets no power, the heat will go full. Could be bad connection even.
