2002 grand prix gt 3.8 mil 130000. My Car Recently got water on all the electrical parts. I drained all the water from it and let everything else dry. I got it running two weeks later and it was running fine but a day later my speedometer would glitch every once in a while and then eventually both speedometer and odometer stopped working. The ABS and Trac off light are on at all times now so I don't know which is causing it between the ABS computer, valves or the VSS sensor. Is there any way to tell what it is, I'd really appreciate if someone can help me

If the lights come on right away there is either an issue with the wiring to the ABS sensors or an internal failure in the ABS computer or valve. You can go to your local auto parts and get them to put it on the scanner and see what they come up with. To me, it sounds like it might be just the wiring. It might have water still in the connections. What you can do is spray a little dw40 in the connections and it will push the water away. Sometimes when people pressure wash they engine the car wont crank back up because of the water.
