step on brake pedal-all turn signal lights come on/dash&mirrors, back of tahoe both orange lens light up-not the red brake ones?
This is happening off and on, or I get system notice on dash-service 4WD or/and stability system service.
What's going on? all fuses and bulbs good.
which come on with the blinkers?
The brake lights are wired through the turn signal switch so its a possibility that a connector has melted and the contacts are touching. That's just one of many possibilities.
Take that back I'd lean towards the hazard switch since all the signal lights come on
When I turn on a blinker, it works till I step on the brake pedal , then the blinker stops and all these other lights come on.
This only starts when the auto-headlights come on or I use reverse which would turn on the backup lights.
Have the wiring checked for shorts, something has gotten crossed over or lost a ground.
