How did we ever get along before the Internet in general and YouTube?
In many aspects of my life, I would be clueless, injured or worse, or out lots of money if it weren't for the information available to us all. Heck, this forum alone has informed me, kept me alive, and saved me lots of money all on its own, thanks to the fine folks here.
The brakes on my wife's minivan went out. The fuses were all intact and the bulbs came on when the headlights were switched on. A video on YT showed me that the brake/taillight bulbs had TWO filaments - and wouldn't you know it, the brake filament on each side had burned out. I just replaced them for perhaps $5 in bulbs and a few minutes of labor instead of spending $75/hr for a shop to do it.
