Under the drivers side of the dash to the left of where your brake pedal hinges there's a small cluster of what looks to be from three to five electrical connectors.

The very top connector on the left only has one wire in it.

The vertically-aligned rectangular-shaped connector to the right of the other connectors is for the Automatic Trans Shift Indicator Control Unit.

You might try unplugging that connector on the right and plugging it back in just to make sure it's seated properly. Given it's location, maybe it got hit by your foot at some point and something happened? And if you're going to check it out anyway, no harm in giving it a good once over just to make sure all the wires going into it are seated properly too.

Wouldn't be the first time an electrical gremlin issue has been solved on one of these VX's by just re-seating a connector anyway.
