yes like stated, start with swapping the bulb out of the other side (check it and make sure its working perfect in that side first). if still no parking lamp (thats what you are not getting, correct?), then check the wires themselves, if they seem ok after a quick look, then pull apart the actual connection plug, take a peek in there see how ugly it looks, stick some di-electric grease in there (it keeps water out, keeps the contacts from corroding and creating a bad connection), and then plug it back in. check your lights again. if still no lights, connection and reinsert a couple times. if thats not the issue then follow the tail light harness under the truck a bit, see if there is any noticeable damage. like stated, if the box has been pulled, look for anywhere the harness might have been or is pinched. also look for splices, and repairs.
these are the most common issues when it comes to the tail light harness. i just had an issue with my daily where my blinker was being goofy on the driverside, when i hit the brakes with the turn signal on, it would blink fast, but the stop lamp and reverse light were kind of blinking (not full light), instead of the turn signal. i pulled the light bulb, and it was fine, pulled apart the connector and bent in the connectors a touch and reinserted. good to go.
