Bob,
If you want to get an idea of what the valve looks like apart then
take a look at the web site below. I have posted pics of it apart. It
is easy to take apart. Drill out the rivet, and twist. It would be
interesting to find out why the valve only works while full on. Mine
didn't leak only while it was fully closed. Have you checked under the
hood to see if the valve is completely closed when the knob is pushed
in on the dash? It should stop leaking once it is full closed and
seated. I ordered a new valve then took my old one apart so that I see
what was going on but also have the ability to replace the valve if I
found something I couldn't repair, or if I screwed something up while
taking it apart. I just didn't want the car to be out of commission
while I was waiting for parts.

Subject: Heater Control Valve Failure?
Well, I put the top up, turned on the heat for the first time since
Spring
and headed to my wife's school to take her out to lunch before
parent/teacher conferences began. I got about half way there when I
noticed
some smoke/steam at t traffic light. Temp gauge was fine so I figured
it
wasn't me. I got about a 1/4 mile further and the gauge started to move
rapidly to the right. Pulled over, popped the hood and coolant was
steadily
dripping from the heater control valve where the temp control wire
hooks to
it. I filled the radiator, let it idle and played with the temperature
control. The leak persisted at any position except full on. So I drove
home
with no problem, except it was getting hot in the car! This looks like
a
sealed unit but I'm tempted to remove it and give it a good flushing
in case
there was just some heater core sediment that caused the problem. Any
other
suggestions?
Thanks
