I don't think you mis-read anything, its just that the situation slightly changed once the blower motor stopped working. Now that I can't recreate the original issue, I'm trying to chase it in a different direction.
HOWEVER. . . With the help of a friend who works here, we managed to solve one of my problems.
On the D137 ECU connector, pin 14 is red/green. . . BUT so is pin 13. And pin 13 is what controls the blower fan!
This issue was completely my fault as the installer.
The blower relay no longer has any authority over the HFS-3 unit.
Now, I just need to figure out what I shorted out to make the blower fan not work.
Richard, as always you were an incredible help. Its not often that people offer such stellar customer service. I hope that you didn't lose any sleep last night over this!
