My 95 Cherokee is has been running well but today it won't start, the battery only works when the keys aren't in the ignition(yes that's typed correctly) and the brakes are locked up. It won't turn over crank or anything! I tried jumping it just for the hell of it, but nothing happened.

HELP!

Auto 2wd if that helps at all

 

Thats by far the wierdest thing ive ever heard. Theres somthinh definatly screwed up on ur jeep mb ur computer is bad and freaked out ?

 

Ended up being the ignition switch. Replaced it and all the issues went away. I had originally thought computer issues, thankfully it wasnt.
