I justreplaced my door lock actuator on my 2003 Lexus RX300. A rather comprehensive set of instructions for removal of the door panel can be found at: clublexus.com door+panel+removal

To remove the door handle trim: after removing the screw in the door handle trim, pry (I use a painters 5 in 1 tool) the trim piece outwardsfrom the rear of the door panel at both the top and bottom of the trim piece. This will release the two small rear clips. Then push the trim forward to release the main clip located on the back side the handle trim piece

As the least expensive OEM replacement door lock actuator for Lexus RX300 is $230 or more, I opted for the $15 replacement option as outlined below: us.lexusownersclub.com/forums

Keep in mind that this job outlined above is a bit on the technical side.If you aren't that talented, spend the money and order a OEM Lexus replacement latch actuator and do the installation as the OEM latch assembly is not repairable.

Viel Gluck (good luck in German)

I hope helps with this. Good luck.

Remove 3 - 4 screws on fender cover close to side marker light. Pull fender cover out a bit for you to use your other hand to reach side marker light. By twisting on one direction and here you go the light out. Replace new bulb and replace everything on reverse order.

The tall center light is located behind the upper hatch inside panel. There are two panels need to remove. One panel is on the right, the other on the left. To remove the panels you have to use flat screw driver to pry out the panel in several locations. (These panels are secured by several small metal clips.) Be careful to collect all these clips and replace them on the back of the panel. You will need these clips to replace the panel later on. After remove the panels, you will be able to locate the screws on the tall center stop light assembly. Remove those screws and cover. After replacing light bulb. Assemble everything in reverse order. Remember, the metal clips have to set on the back of the two panels not the car body.

open up the rear hatch and remove the panel in the corner you are replacing the blub and then you see small screws or nuts that you have to remove and it maybe the kind you just twist the blub out of the socket.
