Great job in tracking down the problem and thanks for showing the importance of using the wiring diagram as your guide, and writing down each step as you go. Your method also shows the importance of knowing how to use a Power Probe in circuit checking, and the importance of a visual inspection of every wire than is part of the circuit creating the problem. I've heard that rodents like to eat wire insulation in a number of vehicles made in the past 30 to 40 years, because a lot of it is made with soy and other vegetable matter that rodents love, instead of petroleum based plastics, which rodents don't like to eat. Car makers think they are going "green" and favoring the environment by using vegetable-based insulation in wiring harnesses, but the opposite seems to be the real truth. They are creating problems their scanners can't figure out, making the cost of car ownership unnecessarily high when the Techs start replacing expensive parts, because they don't understand the real problems, which include bad factory wiring, rodents eating the wiring and corrosion in the connectors, which they seem to have never been trained to understand or fix. Repairing a wire is a low profit item, compared to the profit from replacing an expensive part. Thanks again for the excellent video.
