How to solve a problem when car wont start but battery is good

What you are going to see in this video, is a sample not for you to do it. This will be applied more to these types of models that I will put below, but anyway look at the fuse panel of the car model you have and see if it is similar, the question is that no stay passive when your car breakdown in the hightway, the car does not give crank to start, if you do not know anything about mechanics, do not do it and if you know mechanics and you do it, it is your responsibility if you do somenthing wrong or you don't know what your doing. Ok this is models: Chevrolet Silverado, GMC Sierra, Sierra Denali from 1999 to 2006 and classic models of 2007, Chevrolet Suburban, Chevrolet Tahoe, GMC Yukon, Yukon XL, Yukon Denali from 2002 to 2006, Chevrolet Avalanche from 2002 to 2006.
