Car listed above 3300. Computer is bad (among other things) and needs replacing. Cannot find a diagram of its location online. Suspect it is behind glove box inside vehicle, but would love to know for sure before i start taking stuff apart unnecessarily. Can anyone offer an exact placement so i can access and switch the unit? Thanks in advance.
