When I use my right turn signal all lights flash including hazard lights.
Switch? What puts power to your lights? When you turn on one switch and they all come on, there is power being sent from that switch to all the circuits. Change out the switch and see what happens.
I know it sounds way to simple but change out your signal lights one of them is getting to hot due to a short in the bulb/connection. I had this issue on my 2003 z71 it wouldn't happen all the time just after about 15 minutes of driving in town(making turns obviously) it would happen and it wouldn't go away till about 40 minutes later or shut the truck off. I tested my signal switch wiring etc. finally I replaced the bulbs as a long shot and I haven't had the problem in 2 years
