Unless you are certified by the EPA to handle refridgerant, either leave this one to the professionals, or take the vehicle to a shop to drain the refridgerant. It is illegal to handle or dispose of the refridgerant unless you are certified by the EPA. With the refridgerant removed, # Disconnect the negative battery cable from the remote battery post located near the right strut tower. CAUTION After disconnecting the negative battery cable, wait 2 minutes for the driver's/passenger's air bag system capacitor to discharge before attempting to do any work around the steering column or instrument # Remove the instrument panel by removing or disconnecting the following: #* Shifter knob Allen screw #* Both instrument panel end covers NOTE On the LHS or 300M, remove the center bezel prior to the shifter bezel # Using a trim stick tool, gently pry upward on the shifter bezel; then, disconnect both wiring connectors and a light bulb socket connector; then, remove the socket. # Remove the 2 lower instrument panel cover screws (outside end) and disconnect the deck lid release switch wiring connector. Pull the lower instrument panel cover rearward releasing the clips. Remove the cable-to-brake release handle.
