im working on a 2008 jeep commander for my neighbors wife. she got home last night and left her window down because her child was still in the car. when she turned the key to put the window up nothing happened. i went over to check it out. i disconnected the battery for ten minutes. the reconnected it. turned key on and you could hear relays clicking under the hood, the instrument panel lit up and flashed (transmission over temp, and service park assist) but nothing else electrical would work and i could not get my code reader to work. i tested the battery voltage with the key off and it was jumping from anywhere between 2-12 volts. i hooked up jumper cables to her jeep and everything started to work fine. code reader did not pull any codes and the trans over temp and service park assist messages were no longer flashing. the jeep would not start only the starter would click even after 30 minutes. i am having her  get the battery tested today but other than that i am lost as to what the problem might be. her car was only turned off for 5 minutes before this happend.

sounds like this may be electrical in the ignition, if the the jeep is equipped with anti-theft there is a possibility that may be the problem. there is also a nuetral switch that could be bad, other than that i would say check the fuses and relays. hope this is helpful but you can also check on youtube.com for some ass. keep me updated.

Well I put in a new battery and it works fine now. I have no understanding as to why it did what it did just because a dead battery. I'm totally lost and I know it's fine now I just really hope it does not leave her stranded as her husband is deployed. Thanks for the quick response!
