We have a chevrolet express 1500 year 2002. When the brakes are on and the van is off the tail lights turn on, the thing is when we turn the van on and head lights on the tail lights don't turn on at all. DOES ANY ONE KNOW what we can do to fix this any ideas.If any one can tell us how to re wire or fix this in anyway we thank you so much.

My problem was the brake lights not functioning when the headlights were on. My fix: After numerous test of the rear wiring harnesses both right and left (checked for wire continuity and shorts), I found a short in the rear wire harness on the passenger side (actually the short was in the brake light socket itself). I replaced the wiring harness (autozone Part #923-015 - $22.99) and now the brake lights work properly. I'm a happy camper now. Good luck, hope this helps.

Tail lights would go out or high light worked, but low light didn't, bulbs were not blown. AFter inspecting the housing found that GM would spot weld the ground through the plastic housing to the wire. Both sides ultimately failed. Ended up cutting through the lamp housing, cleaning off the molten plastic and making a good connection to the ground.

Taillights ,and/or brake lights have bad bulb sockets . I splice in new napa replacements($22.00) ; worked fine after that. Or buy factory 3 light wiring harness 100+ dollars.

Bulb sockets corroded in both rear taillights causing issues with braking and tail lights when headlights turned on. When driving, lights indicate bright. When braking, lights dimmed. Just the opposite of what lights should indicate. replaced wiring harnesses on both sides. Problem solved.
