Re: [DML] Heater Problem

["K Creason" <dmc4687@xxxx>]

In addition to the other things already mentioned it could be the AC mode
switch or the little vacuum actuater towards the front of the engine.
When my AC mode switch failed it wouldn't switch from vents (different
problem) and also wouldn't allow the hot radiator fluid flow into the heater
core.
DMCJoe told me to disconnect the vacuum hose to the actuator, and sure
enough it had suction. Leaving it off allowed water to flow into the core.

You may not have a failed switch... after all you are only complaining of
one symptom and I would expect you to have at least one more if the switch
were bad. But it's one more easy thing to check.
