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.

You've possibly crossed your wires at the steering column.

I had this problem, there is four connectors behind the rear passenger tire if you unplug them and clean the connections it will fix your problem.

I have a 2003 Chevrolet Tahoe on the driver side front blinker to left mirror and back signal on driver side comes on when steps on brake. Please need help for the problem. Thanks

My guess is your ignition switch. Not lock cylinder but ignition switch harness under coloum ... Chevy is notiorus for that. I've put about 3 in my 95 ,6.5 diesel Silverado When they start going bad all kinds of crazy stuff happens..

CHECK THE TAIL LIGHT JUNCTION BOX LOCATED UNDER THE PASSENGER SIDE REAR. ITS A SQUARE BLOCK THAT HAS 4 WIRING HARNESS CONNECTED TO IT. THEYRE ANYWHERE FROM $12 TO $40 ON LINE. YOU CAN ALSO TRY O'REILLY'S

Had this happen on a Chevy Astro. The flasher for the emergency flashers was bad. After changing that, the problem was solved.
