When I have car issues that I think I might want to tackle myself, I'll start hunting through the u-tube videos and watch a bunch of them. That way, you can usually get a pretty good idea of what to expect, and even see the problems that people run into. Then, just like on-line recipes, combine several videos to get the best picture of the issue.
Case in point, my in-law's Mercury Marquis had a bad power window. I just bought the motor, thinking I'd try that first, and if that wasn't it, buy the actuator. They sell the motor, or the actuator, or the entire motor and actuator already assembled..... well, I watched a couple videos of just the motor change, took it out, and the actuator spring went BOING! Watched some more videos, and found that it's just easier to buy the whole thing already assembled, drill out the rivets in the glass, and put it all back. So, it pays to watch many of the videos, as you'll probably catch something the other guy missed.
I got pretty good at that window repair, as my kid has a Mercury Sable, and it's basically the same thing. So it now takes me about 15 minutes to remove the door skin, the moisture barrier, drill out the rivets, remove the old actuator/motor assembly, reinstall it all and off you go! I've replaced several on those two cars over the years now.
I've done a few videos myself, but just for fun and informational, and not purporting to be educational at all.
