I have a 2008 6.4L kingranch supercrew with about 55K. All recalls up to date and no problems as of yet except until recently. The problem is when im driving at any speed with the wipers on in at any rate, the needle on the speedo with drop 5mph everytime the wipers cycle. None of the other gauges or tach move, only the speedo. I checked the under-dash fuses and all are good.
Has this happened to anyone else? what could be some things to check rather than having to let the dealer charge me for somthing i can do myself?
