Hi! I bought my jeep rubicon a few months ago and it has driven great. In the last week or so there were some occasions where when I turned the key radio, lights etc would come on but it would not crank. No noises or anything, almost like the battery was dead but it wasn't (I did try jumping it but that did not work). It eventually started after I rocked the car a little. Today it would not start even after rocking the jeep multiple times. I checked fuses, tried jumping it, disconnected then reconnected the battery and tried just giving it time but nothing worked. The only sound I could hear at all is a light click from somewhere behind the glovebox when I turned the key. Any ideas on what would cause this, I worry a mechanic will run all types of expensive tests only to find out it something simple, easy and cheap. Thanks!
