At first, I realized the turn signals didn't work. No lights on the dash, no clicking, nothing. Checked fuses and they are fine. I continued driving the vehicle and realized there were more items that stopped working. Cruise controls no longer worked (it did prior to flashers going out), 4-wheel drive no longer works, center overhead display in-top, and door chimes when vehicle is running, and door is open. Thinking this is an electrical problem that talked to all of these components but unsure where to start. Again, all of these items worked prior to the turn signals going out.

Yep, it sounds like the GEM when out which is common in these vehicles. The GEM is easy to replace because it-self learns, here is the location so you can change it out to fix the problem. Check out the images (below).

Okay, so, I finally got a refurbished GEM. Disconnected the battery hooked up the GEM reinstalled battery and no change. Is there a test I can do to check wiring?
