High beam headlights

[2016 Sierra SLT]

I have a 16 Sierra, the high beam headlights have stopped working, this happened after installing a cold air intake, fuses are good and the indicator  light on the dash comes on, any ideas?

Could be the relay in the under hood fuse box has failed?

 

Problem with a lot of these relays, is that are not serviceable/replaceable, have to get a whole new fuse box.

I dunno, seems like he might have disturbed a connection going to the headlights while doing the cold air intake install?

Good call, just brought up the UH fuse box because I lost the 3rd brake light on my 2008.

 

It was a non replaceable fuse/relay, forget which it was, but whole FB had to be replaced.
