Hoping someone has a simple fix, found a 2019 Tahoe premier for a good deal and drove a ways to go pick it up. After the test drive I noticed the HUD does not work. Tried messing with the up/down and brightness adjustment. Pulled into the garage and shined a flashlight into the windshield and no green light. Disconnected the negative terminal on the battery and that didn’t work. Is there a secret setting or button I am missing? Can’t imagine a vehicle this new already has a bad hud. Also, dealer thought maybe it could be the windshield as it seems it is an aftermarket windshield but I looked at the name and brand and it says it is a pilkington ez-kool plus hud so I would imagine it is compatible. Hope someone can help! Thank you!
