Symptoms of a bad gem module on your late 90s to early 2004 truck. If you're experiencing any of the following symptoms on your general electronic module, the generic electronic module on your vehicle's most likely fried. Number one, ghost accessories. Your windshield wipers turn on by themselves. Your radio stays on after you turn the vehicle off and pull your key out. Number two, 4x4 failure. You flip the switch, nothing happens, or you just hear a rapid clicking sound deep in the dashboard. battery drain. A shorted gem will keep your network awake and will drain a brand new battery overnight. Nine out of ten times this is caused by leaking windshield. The water actually drips down onto your gem module. So use the Fitment tool on my website, drop your make model, gear in the comments, and I'll help you diagnose the issue and we'll get you set up with a replacement gem.
