[DeTomaso] If it's broke, don't fix it...

[Tomas Gunnarsson]

Chris,

The valve comes off fairly easily and can be disassembled. The seal between body and plunger is only a small o-ring (that I admit could be tricky to remove). Unless the plunger shaft is pitted you may be able to fix this with minimal fuss and cost.

Since I want to drive it as much as possible, I've been driving it during the cold but dry winter days here in Washington.  I flipped "on" the heater shut-off valves I installed but the heat to the cabin was only minimal.

I'm not sure what it even does, since it seems to do the same thing as the middle lever ("floor/defrost" versus "car/defrost").

I followed the cable to the little plunger valve going into what I believe is the heater core.  It wasn't moving, so in a moment of what turned out to be stupidity, I pulled on it as I moved the lever and suddenly it unfroze and began moving as it should.  Except for one small thing; coolant began dripping from where the plunger enters the core.  D'oh!  I've read in the forum and in the newsletters about what a pain this problem can be.

I'm not too worried about the heater, since I usually drive in warmer weather, but I have two questions:
