Hi folks! Having an issue with my 13 lariat.
The 0/9 button on the door doesn't light up the buttons when pushed, but the rest do.
None of the buttons will do anything
even though my code does not use the 0/9 button

bought a new keypad and installed it, same thing. 0/9 doesn't light up. Thinking its a wire between the connector and the door pillar. Anyone got a schematic?

If you bought a new keypad and one of the buttons don't work, it's defective. Every led in the pad is powered by one wire.

I just finished testing continuity from the pins at the connector to the bulk head at the drivers door pillar. All have cont. where do the wires go from the door pillar?

Thanks for the schematic! Im having a hard time believing the new keypad is the problem, when it is doing the EXACT same thing the original is. That being the 0/9 button does not light up.

Just because a part is new don't mean it'll work. I've had to return many defective parts to the parts department when i worked at a Ford dealer and every other shop I've worked in over the last 40 years.

As you can clearly see in the schematic above, every led in the key pad is connected to the same wires.

Yeah ive had to replace new parts before too. I guess I'll giver another whirl! ****ty thing is I bought this one off Ebay about 3 months ago so I wouldn't be able to return it.

Parts like that I wouldn't trust from anyone but a dealer.

Seems to me like im not getting signal from the BCM to the keypad on the 0/9. It lights up when you push any other button except the 0/9. Would explain why the new part acts same as the old one.

Where is the BCM?

FOUND IT!! the yellow/green wire that runs in the tray at drivers door sill is broken!! So as i thought, i was not getting signal from the BCM to my 0/9 button!

Which tells me the BCM must be behind the back seat!

The part was a new sealed in box FORD part. Not jobber
