Driver Side Rear Running Light and License Plate Light Not Working, '99 Chevy S10, Blinker and Brake Lights Work, Wiring Issue

Asked by Mar 19, 2017 at 09:41 PM about the 1999 Chevrolet S-10

Question type: Maintenance & Repair

My 99' Chevy S10 rear driver side tail light won't work as well as driver side
license plate light. I checked fuses under hood and in cab, they are okay. I
checked the the tail lights and replaced them and those work fine. When I
turn on my lights at night however the rear driver side tail light wont work. I
checked under the car and noticed the previous owner had done some
wiring work and it appear corroded. Following the wire to the corroded spot
I removed the tape and found the wire had split. I reconnected the wires,
tied them together and taped it up and it still doesn't work.

Attached is a picture of what I had found prior to reconnecting the wires.

Any suggestions? Could it be more corrosion elsewhere? What am I
looking at to get this fixed parts wise myself or price wise at a mechanic?

I believe your problem is right there. When a wire gets corroded, it would need to be cleaned good. That is brown wire to brown wire, thats where it goes, just try making a better connection. Should use a test light to see if there is power there. To have a mechanic look at this, it should take him long to repair this. He'll also check the rest of the wiring and the bulb socket. Shouldn't cost that much.
