The aim is to detach the entire fascia of the center dash, from the hazard switch to the bottom of the heater controls.

Remove the radio

Remove the 4 switches and/or blanks above the radio by reaching in through radio hole and pressing them out from behind.

At the top of 2 of these holes you will find a small Phillips head screw. Remove these two screws.

There are two more screws, placed vertically , in the bottom of this panel. They are accessed from the storage compartment in the head of the center console. You cannot see them, one is on each side, you must find them by feel.

With the panel free, pull it forward gently.  Your aim is to move the panel about 1 or 2 inches away from the dash. There is no need to disconnect anything other than the switches you removed earlier.

Look at the right side of this assembly. You will see a section of white plastic on the side of the OBC. This is the light board.

If the back light has not been replaced before, the side of the black fascia will be blocking this light board. You will need to cut away the plastic that is in your way. Do this very carefully, use a butane hot knife, or a razor knife will work just as well, only cut away as much as is needed to free the light board, be careful not to damage any visible areas.

Once the white plastic is clear, grab the center ridge of the light board with a pair of needle nose pliers and pull it out, directly to the right of the car. If it has not been changed before, it will offer resistance, your force will break a small tab off of the light board, this is ok. You need to remove the same tab from the new light board and slide it in to the OBC.

At this stage, it is good practice to turn the ignition on to test the lights.

Installation

Install the two screws in the bottom of the fascia first.

Test switches after installation.
