Does everything work when the truck is idling?

Welcome to RF!!!

 

[FuqARam]

Yes but lights all flickering

99 times outta 101 it's gonna be the ignition, some can be taken apart and cleaned. I don't know if they still using win module for 2019, but whatever they are using I'd look at ignition first.

 

[FuqARam]

Ok because it only does it when engines running on ignition is in the run position without motor running and for whatever reason I cannot get fogs to work at all

 

[FuqARam]

Also the ignition is the push to start

You mentioned that all BULBs are new ..

Did you replace them with the original bulb type or did you do a Up Grade

 

[FuqARam]

Was a up grade but the factory halogen do it to witch is y I swapped them out

Headlamp switch would be something to check.

Mine failed in my '15, but I didn't have any flicker, just out in 1 position.

That being said, it is an electronic part and bad solder joints and such can cause funky issues.

Definately sounds like a loose connector/ bad connection, tho.

Did you go led? You need to get a balast or similar if you upgrade to led.

 

[FuqARam]

Yea I’ll have too go to that next then probably ignition and bcm I guess until it fixes

 

[FuqARam]

Yes but has them built in I bought the silvaina leds with that built into the wiring

 

[Burla]

Did they flicker before you switched the bulbs?

 

[FuqARam]

Yeah
