I have a 2014 Mazda3 and I love to make videos for YouTube. Mix the two, and suddenly I'm slowly building a library of maintenance tutorial videos for the Mazda3. Here's what I have so far:

Cabin air filter (pollen filter) replacement:
Replacing the windshield wipers:
Replacing the engine air filter:
Replacing the rear windshield wiper:
Brake light switch replacement:
Spark plug replacement:
Coil pack replacement:
That's all I have at the moment. If you live near me (Fairfax County, Virginia) and has a project that you'd like to do to your car, contact me to discuss doing the project as a video. You buy the parts and we'll do the work together, shooting a video in the process. I would enjoy making videos on doing brakes, shocks, struts, hatch lift supports, lamps/lights... all the usual maintenance stuff. You can contact me through my web site: bobkovacs.com

I hope you enjoy the videos!
