So I came out to my truck a week or so ago at night, started it, and turned the head lights on but the cluster didn't illuminate. Seemed odd but my headlights were still on so I pulled away, about a mile up the road I heard a click and the cluster illuminated. Now this has happened a few times but relatively after the truck was on the move the cluster would light up. I realized last night after about 30 minutes of driving when I went to stop for gas that none of my rear lights were lit. Is there a relay that might be on it's way out, a head light stalk issue, or is there possibly a wiring issue somewhere in the truck?
