you must remove the door trim panels. the speakers are bolted to the door behind the trim panels. there are a few screws and push clips around the edge of the panels.

Replacing a bulb on a Lexus is rather easy but a little involve. You can actually locate the wiring harness by removing the trim panels within your trunk. There are typically two cargo hooks that screw out found on either side of the trunk opening.
Also, there are Christmas tree push pins found on the trim panels located on the the trunk sides and the upper part of the trunk.
Furthermore, there is a plastic trim panel along the inside front of the trunk that may need to be removed. Bottom line, remove as much as you need to in order to gain access to the tail light wiring harness.
All that is next is to find the appropriate light socket that holds the light that needs to be replaced. Carefully twist the light socket to the left and pull the light out of taillight. Then pull the light out of the socket and place the light back into the appropriate hole and twist to the right about a 1/2 to lock the socket in place.
Then, replace the trim panels, push pins and screws.
In most cases, you will only need to pull the trim panels back far enough to reach you hand in to replace the light.

check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.

Testimonial: "Thank you! You was right, it was not the alternator, it was a 125 AMP that was blown."
