I have a 2015 Silverado LTZ.
Yes, I did swap the correct wires on the "truck" side of the drivers side (or at least I thought I did) but now that I'm having issues, I was thinking that I need to go back & switch everything back to original & start again.
I did not do the passenger side yet, only the driver side. I was trying to make sure I at least got one side correct before doing both.
I'll switch the driver side back to original, start with the passenger side next time & then go from there.
I'm also wondering if there is a wire that's loose in the connector on the driver side also because now when I put the truck in drive from park with the headlight switch in the "on" position, the passenger headlight cuts out completely.
Starting to think I created a gremlin. Hopefully putting everything back to original & starting over will fix the issues.
