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.
