Michael:
A couple of thoughts:
The heater knob is not connected to your damper, or...
It is connected to the damper, but it is connected in the wrong
position so that the damper never actually closes.
Either one of these will allow fresh air to move through the
heater core and into the car. So verify that the heater knob is PROPERLY
connected to your damper.
Also, your heater valve is probably not closing or broken (they
get old and fall apart, kinda like me). Verify that with the temperature
knob fully in, the heater valve is FULLY closed. (On the passenger side
of the head. You can't miss it, it has a hose running from the firewall
past the battery to the valve. It will also have a cable from the dash
going to it.)
If you wish to tinker, you can drill out the rivet holding the
valve together, and then twist it apart. Inspect and clean it, or if the
internal diaphragm is torn replace the whole thing (cheap!!!).
Reassemble and install a new pop rivet.

Subject: footwell heat
Listers:
I took my '76 on a 2-way trip to my suburban office yesterday. It was
the first significant drive since I got the car back from its lengthy
stay in the shop. It was about 92 degrees out. The trip was about
15-20 miles each way.
Soon after setting out, I noticed that my right foot felt toasty. I put
my hand down in that area, and felt considerable heat coming from the
area of the transmission tunnel near the firewall. I thought that maybe
I was getting actual heat from the heater, so I pulled the heater knob
out and pushed it in again. The heat was unchanged. I have never
actually used the heater before (this is Miami, after all), but I did
find a ventilation hose under the dash near my left knee that was
blowing fresh, unheated air. I didn't find the vent until after I
played with the heater knob, but I think that I got normal heat from the
vents at the right knob position, and that it went away when I put the
knob back in.
While my car was in the shop, the transmission cover was removed, then
the trans was pulled to work on the clutch. It was reassembled after
and the carpeting was put back. It looks the same now as it did before
the work. What confuses me is that I have driven the car on this same
trip in similar weather before, and I don't remember any unusual warmth
in the footwell.
Finally, the coolant temp remained rock-steady just below the midpoint
on the gauge the entire time, so the motor was not running particularly
warm.
Ideas? Thanks!
