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

If you activate a switch and something other than is expected godson, there is a short in the system. You either have a lose wire making contact with the signal system on the right side, or there is a short in the turn signal switch. Tracing a short can be difficult especially since cars, unlike aircraft, need to hide the wiring in very tight inexcusable places. I'd first try looking at the fuse box if possible where the wires to both systems meet. Also if the wire both take path through the turn signal switch, try changing it out. Generally the emergency light wiring is a separate wiring run to the lights for safety reasons. Perhaps at one of the lights pictures on the right side has the wires making contact.
