Instrument panel quit today, after a rain storm that dropped 2.4 inches in 24 hrs. Took to shop and had code check done, told there were about 25 codes all related to data link, checked all fuses and all were good and had current flowing thru. Gauges out, information center ( mileage and shifter indicator ) out turn signals work. idiot lights blink off and on periodically, Any one got any ideas? Fuses checked were by drivers door and under hood don't know of any others.
