So the blower motor on your CX-5 is tucked away in a bad spot? The motor on my 2020 and also the 2019 appear to be super easy to access, so I guess Mazda must have done a major change on the later year models.
And I do agree completely that some of the other Mazda model blower motors are very poorly located AFA maintenance goes. My daughter's 2011 3i blower motor was an absolute nightmare to get to, and if I didn't find a trick workaround to the FSM, I'd probably still be out there working on it today. But I guess every model of every make has a few things that causes the guy doing the work to wish he could just light up the vehicle and walk away.
