I am looking for a schematic for a 2005 freightliner business class truck. I am trying to find a problem with the left front turn signals. The fuse/relay box on the frame has a great deal of corrosion at one of the connectors and the left turn signal relay does not operate. The right turn signal relay works fine.

Hi John, My sincere apologies on this. It seems this got lost in the archives. Im assuming by this point you likely do not need the diagrams now... Let me know and we can get this submitted for credit and to be closed.

I actually do need the info. I replaced the damaged Fuse/Relay box (Freightliner calls it a PDM) and damaged connections but still have the same issue.

The problem appears before the pdm. At the pdm I have toggling voltage on the green wire but nothing on the yellow. Any ideas?
Customer reply replied 9 months ago
The rear turn signals work correctly but I cant tie into the rear circuit because of the rear being brake lights as well.

Thanks for the update. If the directional switch and wiring test good as well as the flasher and fuses/relays then the problem is likely software related in the bulkhead module. this would require being plugged into the dealer level diagnostic software.
