Replace the AC programmer, now the air blows where it is supposed to. although the blower speed does not seem to blow as hard as I remember on my 93 Vette
The head unit seems to work properly. No codes (c68)Even when you pull the codes the 00 shows no problems and #9 seems to indicate correctly what it should be doing , when I drop the temp. the #9 shows that the ac is (#2) same with the heater (#4) the heater does work. but the compressor has never engaged. 12 volts direct to the clutch works. I already tried jumping all of the switches.
I replaced the relay.
When something breaks on my 69 GTX it's pretty easy to diagnose and fix.
I guess that is what I get for trying to apply 35 yrs of knowledge from early Vettes and Mopars to a rolling computer.
I usually not one top give up on these things, But any suggestions would help.
I do have all of the FSM and I understand how to read them.
I don't have a tech 1 scanner but I am looking on line for one.
I already replaced the ECM with a rebuilt one.
Thanks
Bob
