Hi all!
I recently ran into an issue where ALL of my interior courtesy lights do not work when you go to turn them on individually. They all come on with the keyless entry or when you open a door, but when you go to turn them on by themselves, such as the rear cargo light, it does not work. Truck is an '03 Expy XLT 4.6L
Lights included are: vanity mirror lamps (both sides), front map lights (both sides), second row map lights (both sides), rear cargo lamp and the Homelink buttons do not work either. All others work fine.
I did some troubleshooting and it seems that I do not have power at the lamp itself, but I do have power coming out of the fuse box (assuming I tested the correct wire and I think I did).
I did recently have an issue where I had A LOT of water underneath the passenger side floormat. I had to drain/soak up at least 1/2 inch of standing water in some places, one of which was the passenger side bottom door jam where the bundle of wires goes from the front of the truck to the back of the truck. Couldn't easily find any corroded wires. Not sure of this would do anything.
Basically what I'm looking for is some advise as to where to look for the cause of the issue. There's a lot of wire in this truck and any way to cut down my options so to speak would be great.
Thanks in advance for your help!
