Fan Speed! 67 4dr HT

["Dick Benjamin" <DickB@xxxxxxxxx>]

He has plain old fashioned po' folks type AC, not ATC - I just heard from
him in a private message.  But he apparently has no manual for it, and I
don't either.  Probably, the high speed relay isn't getting it's drive
signal in the heat/def position, but I need a wiring diagram to figure out
for sure if this is normal or a malfunction.

For one thing, it may be normal for the high speed not to work in other than
AC.  That is the way the ATC control system works, for instance, as the
super-duper blower speed isn't needed for heat/def.
