I am having a similar issue
Today while my wifw was driving our van, all the lights started flashing, kind of like when a car alarm is going off. The head lights, the odometer reading and dashboard lights as well as on the tempature controls. She pulled over, shut the motor off then restarted it, but the problem continued.
I suspected a wiring problem so had her play with the ignition swith, the stering wheel height adjuster, turn signals and such.
When she pulled the wiper switch forward to turn the high beams on the lights stopped flashing. She pulled it again to turn the high beams off and the lights all started flashing again. Back to the high beam position and the flashing stops, back to low beams and the flashing comes back again.
When she got home I held he trip reset buttion and got the numbers 23 and 55. I tried again this time holding both the Odometer reset buttons till I saw the word CODE and ran the onboard diagnostic with the engine running and the lights still flashing, but did not get any other codes.
We brought this van used a couple of years ago and it does not have an aftermarket alarm system that I am aware of. I am also unsure about anything factory installed.
