earlier this week got in my truck and key wouldnt turn. disconnected the battery and waited about 2 minutes, reconnected and started up fine. A/C would not come on and air suspension went inactive. next morning started fine, A/C and air suspension ok. later that day key wouldnt not turn again. once again took the battery terminal off and waited, started fine. Now side light message appearing and almost every time you turn off the truck you have to disconnect the battery to restart. a stealership telling me its the steering column and the ignition switch. seems like an electrical problem to me but i'm no mechanic. Help Please!
