Does anyone know if the passenger side foot well has ambient lighting? I could have sworn it did. My passenger side has the rear, under door sill area and the handle lit but the foot well isn't.

Pretty sure it does and I'm just now noticing it went out. The glow on the floor is from the storage area of the door card and not from the actual foot well like on drivers side.

Yup, it should. Cycle through the different colors, maybe the red LED has failed?

Thanks everyone. I tried cycling thru the colors and it won't go on so I'm assuming it is the led or some wire. Still under an extended ford plan so I'm gonna give the dealership a call today.

Yeah I don't know how the specific part is constructed that's used for our ambient lighting, but if it's like most multicolor LEDs, it's actually just one LED (or set of LEDs) that puts out the color, but the LEDs themselves are actually multicolor, vs one for red, one for green, etc. Usually the frequency of the pulses (very rapid) to the LEDs determines the frequency. There are a number of ways that could be done, but I'm guessing it's not a one-to-one relationship per-color, per-LED; it would be more likely to be a digital signal to a pulse width modulator, that then drives a multicolor LED (or assembly).

Maybe also check your carpeting, I had your issue and it turned out the carpeting was loose in mine covering the LED. I pulled the passenger door trim and reseated the carpet and now mine shines just like the driver’s side.

I just did the cabin air filter so now that I think of it maybe I hit the carpet pulling the panel/trim off . Gonna check the moment I'm out of work.

I wouldn't be surprised if they finally went with that method actually. I haven't really looked at this generation of ambient lighting closely, but I'd bet you are correct. My old '10 Focus SES was the 3-LED style which is why I just assumed.
