My son has a 2015 truck,the high beams won’t shut off. When he pulls the fuse they shut off,What should we be looking at to find the problem.Any suggestions?
Thanks

i would guess the switch, but it could also be a body controller. nowadays the swithces are all plastic. pull the cover off to see if there are any craked plastic peices in there.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

Disconnect the battery for 10 min or more. Today's vehicles are like computers. They need a reboot now and then. It should also have a relay for high beams. Swap the relay with another similar one.

He told me he tried disconnecting the battery,it didn’t work. He also told me there is no relay on his truck because it doesn’t have LEDs.I don’t know if that’s right or not,will have to check into that.

Here is a possibility but NOT positive.

THe hot wire for normal beam and the wire for high beam Are connected somewhere. where the wire protective shell is too thin or cracked or melted or scraped away.

Allowing the current from normal beam to pass over to high beam
