Crazy LED turn signal issue, HELP!

[JBPS]

So I have LED bulbs in all my exterior sockets (2015 Sierra SLT) except fogs and head lights. All have load resistors installed. Everything came from Super Bright LED's.

 

Last week I had my truck serviced and when I got it back I noticed the passenger front parking light wasn't working, when I used the key fob to lock the doors and used the turn signals the bulb worked fine. It flashed, but no light when the headlights were on.

 

I got a new bulb (exactly the same) and replaced it. Now when using the turn signals, either left or right the opposite sides parking lights flash. Everything except the mirror flashes on the opposite side being used. Its like the hazards are on, only the side that I'm not calling for is dim.

 

This is in Auto headlight mode. If I turn on the parking lights/headlights the flashers work correctly. I re did the load resistors on the passenger side but no luck. Anyone have any ideas?

What service was performed on the truck ?Something came loose/off??

[JBPS]

Oil change, trans flush, tire rotation. Nothing I could think of that would affect the lights.

Loose/bad ground?
