Black screen / stereo JBL stock unit

Hey guys. 2022 premium. I went through a river crossing last weekend and about a week later my head unit is just not working with no warning. I checked grounds and fuses and there all good. Anyone have this happen?

I did notice I’m missing a plug on my inner fender leading to firewall. I’m assuming water got in there and curious if there’s electrical connections in there I can feel a wire. Thanks.

 

Unrelated to your JBL HU but you need to check all your fluids for water intrusion in lieu of differentials etc.

 

With power to the truck on, have you tried holding the Volume button in for 15 seconds?

 

Not 15 seconds I can try when I’m off work. So far if been told to unplug it and replug it in. I’m just stressed there’s some type of electrical connection where the water gets in to the firewall and corroding a connection. I don’t even know if I can access inside that hole besides removing the cowle

 

Are you able to see the backup camera when the shifter is in Reverse?

 

yeah

 

Here are 2 things to try which is worth a shot.

Awesome thanks for the link

 

Please let us know if it fixes your issue or not.

 

None of the tests have fixed it. Looks like it’s going to warranty

 

Glad to hear you are still under warranty.
