AC out defrost vent only on HIGH.

[Ron Wainwright]

 Alex, No there are no codes..Channel 7 is good. Just
may be a vacume leak on one of the lines comming from
the programer to the servos?? Could be the CC head as
well, just don't want to throw anymore parts at it if
I don't have to..even though I do have a few spair CC
heads & servos & such.
 I got V8 stuff to do & building that stroker
motor..so time spent on this takes away from other
stuff.
Thanx
Ron
