tail light not working

Postby twin91 [OP] » Dec 03 2013, 4:50am

I have an 03 gmc sierra 1500 z71. My problem started when I got stuck in the mud trying to rescue a stuck buddy. Now my entire left side tail light and the left side of the 3rd light will not work. Have tried bulbs and fuses but no luck. Everything else electrical works properly and doesn't effect the front lights. Any one know the solution to this? Ground come loose? wiring harness problem?

I would check the wiring harness for any loose connections as well as make sure the ground wire is connected good.
