ok when i got my car like over 3 years ago the check engine light was on. my uncle who i got the car from said it was nothing and had gotten it checked out. i got it checked out too and they said it was some sort of random wire that has a short somewhere around the transmission and it has no effect on anything. recently my driver side window stopped rolling down and my front speakers stopped working entirely. at first these problems only occurred every once in a while but now it happens all the time and they hardly ever work. also when i close my door sometimes all of the doors lock which sometimes results in me locking my keys in the car. does anyone know what could be wrong??? is it related to the check engine light problem???
