Reply to "All 4 turn signal lights flash simultaneously"

Snake...the turn signals are 2 separate circuits. For 'Safety' they are wired Diagonally, I.E. Left Front plus Right Rear to one circuit and the Right Front plus Left Rear on the second circuit. Each circuit has their own Fuse. The safety is...should one fuse Blow-out, there will Still be a Flashing Light on 'That' Side of the vehicle.

You are correct in thinking the problem could be in the Hazard Switch or there is a Short/Connection within the 'Turn Signal SWITCH'. Something has 'Connected' the two circuits into two Parallel Circuits. I would also check the 'Wire Connection/Junction Block', located Just above the Steering Column, and the Fuse Block, itself. With both circuits flashing off ONE Flasher, I would expect the Lights to Flash at a Faster Rate!

Good-Luck in Your Testing!
