We at one time realized last winter we had a major leak from the seeping holes being plugged we had mold inside of our car, now we have cleaned and removed all mold or so we hope and fixed the leaks.We have found that the electronical parts of certain areas rusted and malfunctioned and we got them running but my question is "Why would the speedometer not be working when all other gauges on the dash are" ?I've changed out the VSS already and hooked up a scanner it says all good. I'm confused!!I've also cleaned the terminals on the Black box under the console it had shown to be a little corroded but not bad at all (in my opinion).Edited by: sw2cam
