If you pick up some general electronics and mechanical skills, that will go a long ways helping to understand what might be wrong with your car, or around the house. Just last week I replaced the inducer fan on my natural-gas furnace, with no prior training other than watching a YouTube video. I was able to deduce that the inducer was the problem in the first place, because I wasn't afraid to take off the cover and carefully observe what the furnace was and wasn't doing. And understanding at a high level how furnaces worked in the first place. Of course, to do that, I was able to draw upon decades of experience with all kinds of systems. My training started as a child by observing and helping my father in his workshop. Even so, just having some basic, basic skills and knowledge of debugging [1] can go a long ways to isolate what the problem is and then see if it is something you can fix yourself.
