Hey y’all first post on here since I’ve been working on the companies fleet, I’ve scoured and scoured and have yet to find a definitive answer I’ve checked everything besides ripping the harness apart (understandably so) so both parking lights on the passenger side are non existent, they get no constant power, yet turn signal works fine I checked the pig tail and came to this determination. Is there something somebody has dealt with before that resolved this issue? I’m more of a body tech than anything. This has me ripping my hair out. (And I’ve already replaced the bulb plug)

 

if you post the year and engine size i can check the wiring diagrams.
all exterior lights should be powered by the bcm.
#1 check for body codes...if none
find the wires at the bcm and power the lights in question...if the lights work....the bcm is most likely nfg.
