I have 2013 Dodge Journey Crew 3.6L 4x2 I have a problem with the radio going black when you start the vehicle and when it goes out it take out all the controls, A/C, fan, front power windows and both defrosters. If I put the key in the accessory position the radio and everything else works fine. I updated the radio and tried the 30 minute battery disconnect but the problem continued. I took the vehicle to a Dodge Dealer and was told BOTH TIPMs (totally intergrated power modules) are bad. The one in the Engine area and the one under the dash. Est. to replace $1700. Oh, my radio is bad too.....price quoted for a new one $2800. I can buy both modules online totaling some $300 and the one in the engine area is easy to replace. Anyone know how to replace the internal one under the glove box? Thanks

First I would like to say I read every post in this forum on Black Screens and Radio/Nav problems to solve my problem and make sure I did not duplicate a post. Thank you to everyone the takes the time to help everyone. I have a 2013 Dodge Journey Crew 4x2 with the 8.4" Nav/Radio I turned on the vehicle one day and the radio flashed the start up screen for one second and went black. Does not work to the touch, all controls are dead and the heat in defaulted on defrost full blast. I restarted the vehicle a few times with not change. I hit the forums and started searching for answers and started with the 30 negative battery trick but it did not solve the problem. A week later I started the vehicle and it was on. While it was on I applied another fix from the forums and updated the software from 4.09 to 7.xx (not sure) and updated the Garmin software/database. The next day, dead again. It did note that when the power is in the accessory position or run without the engine running, the unit works perfectly. It is not until you start the vehicle that the screen goes black. Also note that when the screen is black the window controls on the drivers door blink and only the controls to the back windows will work. One day the screen happen to be working while I was driving and it went out right before my eyes. 15 seconds later I heard a clicking in the dash/steering area (like a relay clicking) and the screen flickered a couple times and then came on. This got me thinking the problem is a bad wire, ground, connection or relay but I have been hard pressed for find anymore information on the wiring of the system before I take anything apart and start poking around. If you would have any advice moving forward, I would appreciate it. Thanks in advance
