I have a 2003 e350. No daytime running lights! It's got DRL module from factory. Tried to trace the problem but no luck so far.

DRL to headlights, no short.
DRL to Fuse 5, to battery terminal clamp, no short, fuse is good.
Replace park break switch, nothing.
Replaced headlight switch, nothing.
Replaced DRL, nothing.
I can't find a schematic so that I can follow the wiring from the alternator to the to the fuse F2.6 a 10 amp fuse (which is good).
Are there any other components the current goes through between the alternator to the DRL module?
Where can I find a schematic that shows the current's path from from tha alternator to the DRL module?
I can't get this vehicle insured without this fixed.

Help!

Welcome to the site..


DRL Module power distribution comes through F1.27-15amp BJB and F2.6-10amp CJB

 

You have probably checked this, but have you checked with Forscan to see if the body module is showing the DRLl mode.\When I installed my LED headlight upgrade it always wanted to use the low bean at reduced power dor drl.as the lights had a dedicated light unit for DRL that annoyed me. I went into the BCM and deactivated the DRL then wired the DRL via an ignition feed.
My van is a 2012 so it might be different on yours.
