Strange electrical problems lately.

I have had some strange electrical problems lately, the least 2 weeks. My passenger airbag light came on about that same time. Car runs and drives fine. I had the AC on the other day and the display and AC system just shut off. I was able to turn it right back on and it was fine. Yesterday I tried to open my passenger door and the window didnt go down for me to open the door (Convertible). The day before that i had the drivers side window down halfway and as I tried to open the door it would open cause the window. I had to lower the window all the way down for me to open the door. The key range to unlock is really bad as well. I have to be right next to the car for it to unlock.



I just got my PA soft scanner and haven't loaded it yet to see what is going on. I going to say that maybe my battery is starting to go. Any Ideas?
