Step 1 - Removing the Power Window Switch from the vehicle

Using a plastic trim removal tool (or a credit card),
pry the back of the window switch trim assembly to disengage the clip.

370
Using your fingers, pull the trim upwards to fully release the clips
holding the back of the trim assembly in place.

371

Using a plastic trim removal tool (or a credit card),
pry the front of the window trim assembly to disengage the clip.

372

Again using your fingers, pull the trim upwards to fully release the remaining clips.

Replacing the Surface Mount LEDs

The following image shows the location of the 5 x 1206 SMT LEDs used for the switch illumination.

363

One method used to remove the existing LEDs is to heat one side of the LED with a soldering iron,
and flick the LED side upwards. This method will most likely destroy the old LED, but
it does allow for quick and easy removal without using a de-soldering tool.

364

When fitting the new LEDs, you will need to make sure the polarity (Direction) or the LED is correct.
On the power window switches, the LED polarity is indicated by a K symbol located on one side of the LED.
The K symbol indicates the Cathode (Negative) side of the LED.

Depending on your replacement LEDs, there may be markings on the bottom of the LED to indicate polarity,
(Such as the example below, where the arrow points to the Cathode side of the LED), or there might be
an indication on the top of the LED.

365

Before assembling the Power window switch assembly,
it is recommended that you connect the board to the vehicle, and test the board illumination
to ensure the replacement LEDs are functioning correctly.

366

Power Mirror Switch LED Replacement

The power mirror switch assembly requires 4 x 1206 SMT LEDs

367

Remove the 4 SMT LEDs from the board

368

Again, when fitting the new LEDs, you will need to make sure the polarity (Direction) or the LED is correct.
On the power mirror switch, the LED polarity is indicated by a diode symbol next to the LED.
The diode symbol points to the Cathode (Negative) side of the LED.

Depending on your replacement LEDs, there may be markings on the bottom of the LED to indicate polarity,
(Such as the example below, where the arrow points to the Cathode side of the LED), or there might be
an indication on the top of the LED.
