Hey guys i'm currently having problems with my cobalt. It all started after I got back from deployment. I left my car on base with the battery disconnected. After I got back everything was working fine and then one day it went crazy on me. As i was driving my gauges stopped working. I got these flashing power steering and low fuel messages . I pulled over and turned it off. it wouldn't turn on. after a bit of trying it finally did. a few days later i tried turning it on and nothing, also the stereo will lock itself. lately it goes into power steering while im driving and the gauges go crazy. a weird electrical noise comes out of the stereo too. like somethings crackling. in order for me to turn it on i have to try a few times, let it sit, the it will eventually. i disconnected the battery and put it back on, the trunk light started flickering. anyone have any clue? maybe a ground? and if so where would i check? thanks for your time.
