I just bought a 2006 Mazda5, base model with manual climate control. The blower motor does not work on any speed. The fuse is fine, which leaves the options as the switch itself, the resistor pack, and the blower motor. However, getting to both the resistor pack & the blower motor to check for voltage has proved to be quite the royal PITA - the dash seems to be built around them.
Laying on the driver's floor looking up, firewall at the top, the blower motor and resistor pack are the components with the thicker blue & orange wires running to them
I tried vacuuming out the blower motor from above through the cowl and from below through the access door for the cabin air filter. There really was not much debris in the motor or vents (although there was a mouse nest elsewhere in the cowl). I can reach up through the cabin air filter door and spin the motor's squirrel cage fan by hand, but its harder to turn (and MUCH harder to get to) than other ones I've rebuilt, and it makes a scraping sound when turning.
Cabin Air Filter access door, open, in the front left corner of the pass footwell
My guess is that the motor failed and the bearings went out, or maybe the resistor pack went dead and the bearings in the motor started to rust in place with the blower stuck. Either way, it seems that I need to remove the motor & resistor to check it out, and likely replace them both with the amount of work it seems like it will take.
Has anyone else attempted to get to the blower motor, and if so, any helpful hints about it?
