Dashboard lights

I have a 1998 Dodge Grand Caravan. All of a sudden when I start it four of
the buttons on the dash area under the radio start blinking with their
amber "on" lights. These are the two rear wiper buttons, the recirculation
button, and the AC button. What's up?

The van was just being picked-up from the body shop but they claim they
had not had to pull the battery or dash.

P.S. everything seems to work.
