Begin by disconnecting the ground strap (yellow arrow) from the battery's negative terminal (red arrow).

The trim cover piece is held in place by two Philips head screws on the underside just above the radio (red arrows) as well as two clips on the top (yellow arrows).

Remove the two screws and pivot the trim piece out from the bottom (red arrow).

With the trim piece removed use a Philips head screwdriver and remove the six screws holding the climate control unit to the center console and upper switch plate (red arrows).

On the back of the unit are two multi pin connectors on each side (red arrows).
Figure 7

On the back of the unit are two multi pin connectors on each side (red arrows). The unit is labeled left and right but it is difficult to mix up the cables as the left one has a hard time reaching the right side. Label the wires if you think there will be any confusion. Simply wiggle and pull the connections straight up.

The cover for the switch plate has a plastic surround protecting the wiring from the crash tube behind it.

The cover for the switch plate has a plastic surround protecting the wiring from the crash tube behind it. Squeeze in the four tabs and it can easily be removed (red arrow).

The switches are all individually wired and replaceable.
Figure 9

The switches are all individually wired and replaceable. To remove or replace a switch, squeeze together the clips on the top and bottom (red arrows) and pull the switch straight out from the plate. Installation is the reverse of removal.
