Hi Davey and welcome to the Ford Fusion Club. It is possible you have some LED lights malfunctioning. Is your 2018 Fusion still within the 3 year/36,000 mile New Vehicle Warranty or an ESP Plan?

Good luck.

 

Thanks for welcome! Sadly it has passed the warranty, do you k ow if it’s possible to replace the lights and not the whole assembly

 

I only have 2020 Wiring Diagram, and the cup holder ambient lighting was removed for 2020, but I am sure it is the same as all the others, it gets 12v, ground, and a logic signal (which is different than older ones that had 3 RGB wires to each LED). I would guess there is an issue with the module itself. Not knowing enough details on the new setup or where it is, I don't have any better ideas.

 

Part number for the cup holder modules is HS7Z-14A318-E

Hello! 2019 Ford Fusion Hybrid Titanium here. Did you ever find a solution to this?

I'm having a similar issue that started exactly like yours last night. But it has now also spread to the foot LEDs- both of them and the console LED are not turning on at all. The passenger door now sometimes changes to whatever color it wants. Cupholder now stuck on blue.

I suspect a fuse but can't find the ambient lighting fuse on the diagram. Looks like that fuse in the 2018 model is in the #1 position on the passenger compartment fuse box but it says that one is unused in the owners manual.

You'll have to scroll down but here's an online guide I found- it shows the 2018 Ambient Light fuse, but not the 2019 or 2020

i’m also having the exact issue. cup holder started glitching out and then all ambient lighting went out except the doors. did you end up finding the culprit? i don’t feel like bringing it in to the dealer for this lol! thanks

 

Can anyone tell me if there are ambient lights in the rear doors of the 2018 Fusion Energi? Our ambient lights in the front doors work, but the 2 back doors are dark. The dealer is telling me there are no ambient lights in the back doors, but I want to be sure.

 

So apparently, if the wiring for the cupholder has a short, it may cause everywhere else, except the front doors, from lighting up. I saw someone cleaning the cupholder wiring, but the disassembly is too hard so haven't tried yet.
