my left headlight has stopped working..both high and low beam. I checked the auto fuse for the left headlight and found it to be good. I have voltage at the fuse location. I ohmed the low beam connector and it is not grounded and I do not have any voltage at the connector. any suggestions would be appreciated.

I don't know about newer chassis , but my 99, F/L has a relay for each headlight .
Relay active for high beam , relay inactive for low.

If your chassis doesn't have this system , time to call Freightliner's free help line, for your chassis wiring diagrams and schematics.
Have your chassis serial number handy when you call .

Thanks. Did not look in the relay box. I Hope I can exchange the left and right headlight relays to see if that is the problem. I have my annual inspection due in July so it would be nice if this was the problem.

Skip, I could not find a relay box like yours above my generator and beside the fuse box. Unless someone can direct me to the location of the left hand headlight relay I will have to give Freightliner a call tomorrow. regards, jim bass

In case it's helpful, here's the Auto Lamps Wiring Diagram for your coach.

skip, ended up calling Freightliner and I was told my 2006 journey I had a (blue) lighting control module, 7.5 x 4 inches. I found it under the dah next to my steering column.
I am going to ohm out wiring to my bulb connectors to make sure there is no issue there and if not, I will order the mosule. thanks for the help....appreciate Chris's wiring diagram, as well...

Just fyi, headlamp module can be seen in VIEW DA on page 5 of the Front End Wiring Installation diagram for your coach.

Thanks for wiring diagram. Using it I noted that left and right headlight power appear to go thru ignition. So when I turned the key on Both headlights worked...but with key off only the right headlight worked. Good news is...I passed my annual mechanical inspection. :-)
