The problem has always been bad light bulbs I never seen anything else go wrong ever, even both bulbs going bad at the same time is ver very common on that truck. The left is kind of tricky to replace without pulling the grill and fascia off but the right can be replaced by removing the air filter box. If diagnostic are needed let me know just have a voltmeter and test light and some small tools. Thanks I hope this helped. Please give a positive rating. Thanks
