The PCM is on the passenger side firewall, however it is quite difficult to see if you aren't familiar with it's location. If you have a skid on the bottom of the passenger side dash, it will need to be removed first. If you can not see the blower motor/wiring, then there is a plastic skid cover there that needs to come out. If you can see the blower motor/wiring, then you don't have to worry about it.

Pull the carpet back from the front edge of the passenger compartment, then lay down on the floor with your head looking up behind the AC duct work

You will see a black box with 5 connectors sticking out of it; this is the PCM.
On the bottom end of the PCM is a metal bracket with a single 10mm bolt/nut holding it to the firewall. Remove this bolt/nut, then grasp the PCM and gently pull downward
The top of the PCM is held in with rubber grommets that it will slide right out from, and there is usually enough wire harness to leave it plugged in laying on the floor.
