Hank, if you have the same as our 2014, here is what we found.
I understand that there has been at least one other person with the same issue.
The keypad has 4 wires. Red and black are of course the 12v power. (check for 12v here
Brown/white and Green/white are the 'control' wires.
Do you know where the Control box is? Back of the storage bays on the ceiling/under the floor.
The Brown/white wire is on the corner of one of the two multi-wire plug connectors.
Mine pulled totally out of the connectors when I pulled on it. It was not crimped well.
IT WAS ON THE CHASSIS SIDE OF THE CONNECTOR.
I just pushed it back in until it made contact and now the jacks work.
I will do a permanent fix later when I get a tool.
Mine keypad was also acting strange for a few days. Lights would not come on when I pushed the power (or any) buttons. If I turned the key on, it would light up and indicate 'key on' but still would not respond to key presses.
I assume the slides are still working?
