Blower Motor assembly installation for the heating/AC system.
The blower motor for the heating/AC in my 2016.5 CX-5 GT failed. Replaced the blower motor assembly along with a couple of fuses.
In my case, I also replaced two of the heater/AC related fuses in the engine bay's fuse block, as a precaution (even though they were intact and not 'blown'), as many of the original fuses are showing their age and fragility:
After the swap, the new blower motor is working perfectly. Probably didn't need the new fuses, but as inexpensive as they are I preferred to be proactive. Might well swap the whole bunch of engine bay fuses, given they're all fragile and showing their age. "Cheap insurance", IMO. Need a few more spares anyway.

In my case, I also replaced two of the heater/AC related fuses in the engine bay's fuse block, as a precaution (even though they were intact and not 'blown'), as many of the original fuses are showing their age and fragility:
- #19 fuse -- 40A (Air conditioner/heater); and
- #30 fuse -- 7.5A (Air conditioner).

Parts:
- Existing blower motor assembly, at least for my 2016.5 CX-5 GT: P/N KD45-61-B10, Blower Motor (Mazda OEM)
- New blower motor assembly: P/N PM4106, VDO/Continental aftermarket brand, purchased from RockAuto
- Note: This procedure takes about 30 minutes, from start to finish.
- Turn the ignition OFF.
- Ideally, disconnect the NEG cable from the battery terminal.
- Remove the glovebox door assembly -- open the glove box, press inward the two fat tabs at the upper-left and upper-right of the side of the glovebox door, then unhook the stopper arm located at the lower-right of the door.
- Remove the underside plastic cover (below the bottom of the glovebox door) -- press the two tabs at the front of this cover, then remove. The blower motor assembly is now accessible.
- Disconnect the harness from the connector on the blower motor.
- Remove the 3 screws from the underside of the blower motor that hold it into the bracket. The existing motor assembly can now be removed.
- Install the new blower motor assembly, install the 3 screws, attach the wiring connector to the blower.
- If the NEG cable from the battery was disconnected, reconnect it.
- Turn the ignition ON, then check function of the heater, A/C, and the blower motor's speed functions.
- If all is working properly, "button-up" the lower panel and the glovebox door.
- For the first hour or two of operation of the new blower motor, expect a bit of 'new parts stink' to come through the heater/AC vents. Recommend keeping the windows cracked open while this processes continues. In my case, it lasted for the first hour of operation.
