Thanks for the info. Unfortunately my manual only goes up to #88 so im not sure where #158 would be?

I did do one more test with fuses #25 and #26. #26 fuse reads 12v, but #25 is 0. I have put a brand new fuse into #25 and even put the fuse from #26 into #25 to make absolutely sure the fuse was good. Reading 0v no matter what.
Look in the engine compartment- the big fuses (maybe a circuit breaker too IDK) is in the engine compartment

Fuse 158 powers the RH headlamp. In the pic, it is in the top left, second row of the smaller fuses. Hopefully you can zoom in to see it.

Okay yeah in my owner's manual that is #25. Thats the one that's giving an issue reading 0v even with a new fuse. Thank you for helping me though.

So for anyone else that will experience this, the headlight module needs to be flashed to the cars bcm. The headlight lighting up for a few seconds when I plugged it in was a complete fluke. Took it to the dealership for them to flash it and it works fine now

Thanks for the info. Pretty sad when you can't change a headlight without programming.
