 |
|
I'm still screwing around with my heater control for my 77.5 N/A. If I'm reading the wiring diagram right, it looks like the two wires that go to the control are grounds. This is kinda weird because the two wires that aren't spoken for are hot and push 12v and are always hot. BUT...if I touch a ground wire to the board, the fans come on. Does anyone know if these two wires are right? I was thinking that maybe the cables that attach to the board may also create a ground, sound right? Thanks for the input.

The heater wiring is kinda weird on these cars as the fan comes on (very slowly) even when the fan switch is turned to zero. Don't let that confuse you.
