RE: quick and dirty fix for 5kq? CC (update)

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

... you know ... I thought that forcing the heater valve from the rest
position actually closes the valve ...

On the 5kq the climate control system usually allows coolant to flow through
the heater core (it also runs the refrigeration system as well!) and then
uses the blend doors to regulate the air temperature.  Based on this fact I
don't see any reason that you're using a pipe to replace the heater valve
wouldn't be a totally acceptable solution.  The only time that the
controller shuts off flow is when you have the system set to "AUTO" and the
temperature set to "LO" or the "OFF" mode is set.  If you find that the
vacuum line that drives the heater valve does not hold vacuum, it indicates
to me that your recirculation flap control motor has broken itself loose of
its mount.

HTH and stay warm!
