Anyone ever have issues with the ambient lighting?

I just realized that the strip in the front passenger door does not illuminate; other three doors are fine.

Anyone every troubleshoot this?

 

You have to take the door off (3 screws only) and then take off about 15 screws (it's really more like 18). Here is a picture of when I did a swap of my GS350 trim with the GSF trim.

Here are the screws you need to remove for clarification. The light strip is attached to it.

 

I figured out my ambient light issue!!
The passenger front door ambient strip didn't illuminate.

According to the service record, there was an issue with the passenger side blind spot detection, and the dealer removed the door panel.
He didn't do a very good job: nearly half of the pop clips around the panel were broken or missing. I had spares.

First things first: where is the plug for the ambient light? Here it is:


Okay. I don't actually remember unplugging that.

Let's inventory the wires: door handle light plug, seat memory plug, window switch plug.


Wait a minute!! I am missing a wire!

What's going on in here?


Could it be? It is! The missing wires!


And lo there was ambient light!


This is why I work on my cars: there's no guarantee of care, especially with time pressures.
