Hey guys, I've just rewired my fusebox back to factory according to factory VN V6 wiring diagrams. All modules seemed to be working right so far, haven't tested EFI relay or starter relay because no motor.
-Headlights both working
-High beam both working
-Parkers and indicators all working
-Fuel pump working
Now. I rewired my engine fan relay because i want it to activate automatically and the guy before me had some sorta dodgy positive bypass onto the engine plug.
now my blower motor doesn't work at all. And when i remove the engine grounds from the head (i have sitting on ground to trick it into thinking its an engine block)
the relay energizes but activates the radiator fan when i operate the blower controls.
I have checked the ECU pin for blue/white wire and it is on the correct pin.
I have tried 4 different ones of the same relay.
I have inspected the dash loom and appears to have not been tampered with.
BCM has melted A/C pins as I've seen on here before and the previous owner has already bypassed it with a Narva add-a-fuse.
How do I fix this??????? I have compared it already to a HSV LE VN 5L and found the engine fan relay to have identical wiring even though it has no electric fan.
Pin 30 orange/white power
Pin 86 pink/white to blower controller
Pin 87 orange/pink to engine fan
Pin 85 blue/white to ECM
What have i done wrong??
