Tachometer jumpy when using hvac
As the title states, just purchased this truck a month ago. Tach was on the fritz, at 70mph it was pegged in the redline, put a new tach sensor on it, seemed to clean it up a bit. Im starting to pay closer attention to it and notice when i use the lights/ hvac or anything electrical in the cab...- KHull
