**DUMBASS MISTAKE ALERT** So a few years ago I followed a post on this forum to wire up raptor lights in the grille of my 2016. The post suggested tapping into (I know, I know...) the HI beam headlight harness which I did, and the raptor lights lit up, but after that point the HI beam / DRL bulbs never worked correctly even after removing the stupid raptor lights.
Lo Beams ON: HI beams
don't light up with push or pull of stalk; dash indicator does light up.
Lo Beams OFF: HI beams
do light up with push or pull of stalk; dash indicator does light up.
DRL position on the stalk never works. IIRC the HI and DRL share the same bulb so guessing related.
I did a check of fuses I thought could be related but don't see any burned out. Maybe it's a relay? I do have TechStream installed on a laptop and thought about trying to diagnose with that?
Any ideas?
