Remove the three screws holding the glove box hinge to the frame and place the glove box out of the way. Disconnect the wire blend door actuator harness and remove the blend door.
Use the pattern in Fig. 3 to cut into the bottom of the heater box with your Rotary cutting tool or hot knife. The cut is made from under the dash panel on the passenger side. There is not much room to work, so it is helpful to have a short bodied cutting tool or aflexible extension attachment. Note that there is nothing behind the cut area that can be damaged. The only critical point is to make sure you do not cut into the round pedestal circled in Fig. 4.
