To any and all,
I tracked down the sometimes open, sometimes short in the #1 circuit. It was
the ash tray wires leading up to the ash tray connector. After years of opening
and closing the ash tray, two wires, one ground and one +12 had severed.
Thanks to all those who might have given me help.
Now how to figure out how to fix the A/C climate control push button box: temp
wheel works; fan works ia all modes; and none of the push buttons do anything.
Air flaps are stuck in the default (no vacuum) mode. The 7 relay vacuum block
works as I can trip each relay by grounding each realy to ground.
