; Always start by looking at Fuses like Jonny mentioned. You shouldn't have to take your car to the dealer for anything, unless you want to. There are products and shops out there for you do do everything yourself or a lower cost professional at an independant shop. If your handy at doing work yourself look into getting the Bently manual that Jonny also mentioned. Good luck and don't be afriad to ask lots of questions because, that's what we are here for.
