Please help. The backlight on my 2009 Expedition for the transmission shifter is out. I may be using the wrong term for it. It is the light next to the shifter that lets you see which gear you are in (P, R, N, etc). I don't know if the problem is an LED or a fuse, but I think it is the only thing that is out, so I am guessing it's and LED. How can I check the problem and how can I fix it?

Welcome to the site. I don't have the service manual for the 2009 but earlier years also used LED's for illumination. I would expect them to be very similar.

You would use a digital multimeter to check the led's. The meter must have a diode setting in order to check them since it needs to put out enough voltage to forward bias the diode. In english that means "turn on". Also the meter would be used to check for voltage on the wiring to the led.

There are 2 bulbs. PM me your email address and I'll send you the relevant pages from the service manual.

I guess I didn't ask the most important question - how do I open the housing to get at the LED?

I sent you the 2 pages. I haven't removed these panels, but it's always good to have a couple plastic trim removal tools on hand if you don't already. Harbor Freight sells a set for $5, Amazon sells them for about half that, and I'm sure more auto parts stores sell them.
