You do not need to remove the entire glove box, just the door. Remove the glove box by opening the door any emptying its contents. Squeeze together the outside part of the glove box that becomes visible while open. Squeezing it will release the clip from its fastener, and the glove box will slip right off. Unhook the connection module that runs from the PCM to the vehicle. Depress the outer clips and pull to release the connection module (It is a six or eight pin white connector). Use the socket wrench or screwdriver (depending on the vehicle year) to remove the PCM from its mounting. There should be six bolts or screws. Keep the bolts or screws in a safe location because you will need them to install the new PCM. Place the new PCM in the exact position as the old one. Tighten the screws or bolts to secure it and then plug the connection module back to the vehicle. Replace the glove box door and reconnect the vehicle's battery. Start the vehicle to make it is operating normally.
