Ok, so today I was driving back home, ~30 minute drive, and out of nowhere The Battery light came on. I kept driving, and about 10 seconds later it shut off. and a few mins later, same thing happend. Anyway I get home, check the battery cables, they were good and tight But the Light stayed on now, I unplug the alternator plug, and put it back in. light was still on, and i noticed it goes off, once the car drops to about ~7-800 RPM

and. my second problem is the driverside seatbelt *automatic* got stuck halfway, and wouldnt go back or forward. so I forced it to the closed position so i can drive home and it will not move now, But i do get the Beep beep beep beep .......

please help
