nostartgaugeswork

Hi all, The past few months I've been having troubles with my Jeep. I've looked around all over and made a post here trying to diagnose it and have come up with it maybe being the TCM. Have one ordered up and it arrives tomorrow! But today the problems got worse. I have driven the TJ 3 times...

When out to leave and Jeep was dead. I replaced the battery in January took it back today they replaced it with a new one. Now it still won't start gauges work,radio but will not turn over. Where should I start and what do you recommend? Thanks. 2003 TJ 4.0 6l
