To replace the back-lighting on your OBC: |
Our aim is to detach the entire fascia of the centre dash, from the hazard switch to the bottom of the heater controls.
Remove the 4 switches and/or blanks above the radio. Using a small screwdriver to gently pry them out usually works best.
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 centre console. You cannot see them, one is on each side, you must find them by feel.
Now that the panel is free, pull it forward gently. Never force anything unless an expert has told you to.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, I use a butane hot knife, but a razor knife will work just as well, you must make sure you do not cut more than you must, and be careful not to damage any visible areas.
Once the white plastic is cleared, use a pair of needle nose pliers to grab the centre ridge 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.
Assembly of the removed parts is straight forward. The best bet is to install the two lower screws first, as they are difficult and it's nice to be able to move the panel slightly to aid installation of the screws.
Don't forget to test the hazard and defroster switches after installing them.
