A few months ago I was driving on the freeway and the A/C, cruise control, and the electronic shifting transmission went out. I was stuck in what seemed like 3rd gear. When I took it in the mechanic said one wire in the dash burnt up and didn't allow the computer to communicate with the car (not allowing it to shift). I had it replaced fairly cheap, and now just the other day it seems like it burnt up again. Any idea as to where I can find the wire and why it keeps burning up?
