Hi. Every morning my malibu 2001 horn starts if it's freezing outside. The head lights doesn't work, neither the remote control for the doors. I can start the engine but the horn still running. I can drive the car but without head lights. When the car gets warm the lights come back and the remote works. When the whether is warmer there is no problem. I want to know if it's the anti thief system or computer problem.
