My wipers stay on and won’t go off unless I pull the 25 amp fuse , and the lights come on every time I turn on the wipers even with the fuse taken out! Any ideas on the problem!!

the wiper motor has a shorted out diode, you can replace the electrical board on the motor or replace the whole motor

- 4 Wheel Drive System

  I doubt two wheel drive pickups are a hot seller off the new vehicle lot in your area !, I highly doubt any of the dealers around here have brought in one two wheel drive pickup for many years as that four wheel drive system isn't along for the ride here or I can well imagine in Vermont during the winter. Of course some of our more poorly maintained gravel roads are so bad that during the summer if it rains a person could get stuck right in the middle of a gravel road in two wheel drive LOL.

  My 2016 Silverado L86 failed at 102,000 miles 2 weeks ago. It doesn’t matter what year it is, how often you change the oil and take care it, it’s going to fail. These engines are a ticking time bomb and GM has known it for over a decade.

  This is a good video on fuel additives and their effects. It's long but well worth the time. Very good information.
- Oil Consumption

  Personally, if it's anywhere on the upper 3/4's of the marked area I'm not adding anything, to avoid the 'risk' of overfilling. If I am close to oil change time, and it's at the bottom of the marked area, I still might not add any. For this to be the case (which it never has) the engine would be consuming an amount of oil that I am no longer worried about the longevity of it.
