I replaced my blower motor last week, by far it was the easiest part I've ever replaced on a car (other than light bulbs on previous cars), 3 screws and a plug. It only cost me about 100 for the part on Rock Auto.
If you haven't lost interest already, it's a royal pain to swap out. You have to remove a ton of screws and clips on the bumper AND THEN two metal rivets to swap it out.
I ran my cables down the A Pillar, making sure to zip tie the cables to the factory loomed wiring and trim the excess to avoid any problems with the airbag. I chose the safest route to avoid the Side Curtain Airbags, which was going down to the doorsills and then to the rear. The only real pain...
That's how I have mine, only mine is actually on the windshield. I specifically got one that sticks to the windshield due to vibration from my subwoofer, I'd never get a clear picture otherwise.
2017 Sport AWD 94,000 miles. Other than having to replace my battery due to not driving it for 3 weeks and negative temperatures, absolutely no issues.
