tried searching the post but couldn't find anything specific, lots of pages......
2017 GMC Sierra SLE
Performed the DL8 to DL3 conversion. Started with passenger side and everything works fine, puddle and signal worked as they should. Completed the driver side and just the signal light works, no puddle lamp. Tested lamp, lamp is good. The only wires I did not run where the auto dimming circuits (from what I read does not affect my issue). Any guesses??? Checked and rechecked schematic and my wiring. My mulitmeter took a dump but I'm confident my crimps and connections are good.
