There are few things more frustrating than to have your trail day cut short by an electrical problem. Jeep did a great job with the modern Wrangler JL and Gladiator in many respects. However, there are some serious weak links that we've experience firsthand. If you've had the dreaded Service 4WD light pop up, you know just how big of an off-road nightmare that can become. In this video, we will show you the commons causes of that light, some ways to bypass it, and what we've done to ours to fix and prevent future issues.
