2007 Ranger DRL's will not turn off. Replaced switch but did not solve problem. Please help with fix.

 

Welcome to the forum

Unfortunately I don't see a separate DRL module that was used prior to Rangers getting Smart Junction Box(SJB), in 2005 I think
SJB is the Body Computer, it runs all the interior electrics and lights, cab fuse box is part of SJB
SJB is in the passenger side kick panel

Wiring diagram for 2007 Ranger with DRL below
Also included wo DRL(without DRL)
So you can see difference in wiring

Looks like Fuse #3 and #4 power the Low Beams so they could be pulled out so battery doesn't go dead

Also on my Ranger if Parking Brake pedal is pushed down with engine running DRL headlights go off, even if pedal is just barely pushed down, Brake light on dash comes on, and DRL head lights go off
Looks like 2007 has same setup, connection to Parking Brake switch, but not sure that would apply when key is OFF
