I am not good at all with electrical testing procedures, but all my rear lights went out. I have noticed for some time a clicking sound when I press the brake pedal. How can I tell if it is not the bulbs, or fuses which I checked, if it is the Turn signal Flasher, or the turn signal switch, or the brake light circuit which runs thru the turn signal switch, or the brake Light switch. I know this is a long post, but if you r experienced I will correspond with you thru email if it is OK.

Check the ground circuit at G415 at left frame rail behind bumper if okay time to open up the turn/hazard switch and investigate

Those back lights share the same ground and if its gone -nothing will come on back there

Good Luck
