Freightliner Columbia Wiring Help Needed

[joshplianfield]

Can anyone help me, I have 2002 Columbia, No power to the furthest (closed to windsheild) stud in the PDM and therefore I have no power to the wipers,blower and ecm.

I can apply power to the stud and get wipers and blower but still no ecm power.

Detroit 60

Mitchell and Motor both suck on this.

I need schematics, location of the accesory relay and possible labeling picture for the PDM as the cover was missing.

Thanks,
Josh

FYI incase anyone in looking

ACC relay is to the closest to the door, in the bottom row in the PDM, held to PDM with a metal clip, the one next to it is the RUN relay.

I'm ok now, turns out the only things the ECM ign power,wipers had in common was the deutsch connector on the fire wall, I unplugged it and screwed it back on, I think the last tech that touched it may not have had the pin lined up and thought it was on there right.

Starts and runs great!


Thanks,
