Bob, in my very limited experience, what happens first is that the valve
itself gets hard to move.  Then the center wire buckles right at the
dashboard lever, producing the condition you describe.  The temporary cure
appears to be to replace both the valve and the cable.

The permanent cure appears to be to re-engineer the thing using a different
valve.  Although I have not tried it, I suspect you could leave the original
valve in place (open) and a dummy length of operating cable through the
firewall; then rig the interior lever to operate a Chrysler-style valve
hidden inside the passenger compartment.  But it's just a thought since I
don't own a TR6.
