Hello, sounds like your regulator is cooked. This thread HERE should help you out.
as far as your steering goes, your steering wheel is not centered, or your car pulls or is wearing tires uneven ? either way, you'll probably want to go and have the front end alignment checked/changed. :thumbup:
If someone hit a curb with it that can mean big problems with your suspention. last year I hit a curb really hard in my pulsar and my alliginment was really bad plus my wheel is now pushed back a little. but the shop I took it to got it pretty straight, you can't even tell when you drive it now.
yea my sentra trys to battle a curb every winter and looses, nothin like changin out suspension in the snow to teach u a lesson, every tiem its for a different reason. ive messed up a different wheel/ suspension for 4 years strait
