Weird problems

Ok so today i started my car. When i got out the driveway i noticed that the airbag light was flashing. A few seconds after that the steering wheel kept going up and down by itself. Then at the same time the radio kept turning on and off by itself. At one point the interior lights kept going on and off. I tried turning it off and back on, but it kept happening. Please help thank you

Sry to tell u ur car needs an exercist not a mechanic. More than likely need a new control unit. There a main ECU that handles all of those things you mentioned and more than likely more. I had one go out in my truck and it cost me 1200 to fix. Find your ECU and swap it. It is possible that the ECU went bad because of a bad battery or u improperly jumped the car or u went to charge ur battery while it was still connected and crossed the cables so figure out why the ECU went bad or else u might end up buying another one down the road

I never touched the battery since ive had the car. I noticed a quiet tick every time the radio would turn off. I got out of the car and located it. I didn't touch any of the fuses and just left it alone. 5 minutes later i went to see if the problem was still occuring and it wasn't. So do i just forget about it now or should i take it to a mechanic? The picture is where the tick was coming from.

Try the ignition switch cuz it is cheaper or get it looked because if it's anything that could be wired into ur alarm u might come out of a store one day and ur car won't start because of that problem. Yea figure it out quick before it costs u an unnecessary tow
