I have an '85 Westy with A/C.  What does the temp. knob do?  Does it
control the cooling by cycling the compressor?  Is it tied to a bi-metallic
on-off switch somewhere?  I would guess in a Vanagon, it is set on "Max"
all of the time anyway. If this part of the switch is bad, could I put in a
separate on-off switch to kick in the compressor?   How much juice does the
compressor clutch draw?
                                                        Any help
appreciated,
                                                        Jay
