check the abs module. they're known for having bad connectors, that get water inside them, and cause all sorts of mischief. the rear axle speed sensor could also be bad. it's about five hundred bucks cheaper than the abs module (located behind the battery)

the speed sensor would signal the speedo, cruise, etc. the abs problem might be solved by opening, cleaning, lubing and reconnecting the abs module.
