I did remove the blower motor (under the passenger's dash w/ 3 Torx screws & one connector) & was able to determine the armature is open & very rusted. I have 12VDC at the connector so there doesn't seem to be any additional electrical problems.
My local Mazda dealer wants $611 for the blower motor over the counter. I was able to find a few aftermarket locations on the web with a $470+ with shipping price tag for the blower. None of the local salvage yards have this part & if they were to get a CX9 in, they would look to sell the entire HVAC unit as opposed to the blower by itself.
My local dealer didn't want to hear my sob story so they sent me to Mazda Customer Service. Mazda Customer Service (aka Sales Prevention Team) didn't want to hear my sob story either but let me know to keep my receipt for the blower as if there's ever a recall for the problem, I would be reimbursed for the cost of the motor.
After owning 20+ vehicles over 35 years, I've never had an evaporator drain tube clog. What's even more disturbing is that the vehicle is less than 3 years in service. I believe it's safe to say this is my first & last Mazda vehicle. :lemon: :lemon:
Rusted: simple sand papering will clear the rust on the "iron" armature surfaces..
Open: IMMHO that is not very likely. If it uses brushes then the brushes will undoubtedly be stuck in a non-contact position, somewhat retracted position, clean the brush holder(s) and see if the armature is still open.
Lightly sand papering, cleaning, the copper commutator segments wouldn't hurt.
If the blower motor uses electronic brushless commutation, as many modern systems do, then I would still clean it up thoroughly and see if now runs. If it doesn't run then the electronic control is most likely at fault.
...even if they look like cr@p!
2007 Mazda CX-9 Touring 2WD (first generation and first year) with 89,000 miles on the clock. Inland Empire in SoCal every summer temps run between 100-115 degrees...not a single problem. Runs everytime ice cold.
what's to lose if you "break" it open.
"..any armature assembly..."
No, the brushless ones would likely indicate infinite ohmage since the commutation is done with transistors.
How did know the armature is rusty...?
Pictures..?
r u near Seattle..?

It is normal that the a/c seems to turn on when you turn off the car?
My car does that sometimes when the outside temperature is high and I dont now if is something wrong...
Just in case..
When we turn left, it sounds like whatever we are moving around in the dash makes it hard for the fan to function properly and the air coming from the vents comes almost to a stop.
Has anyone run into this? We are out of warranty and will have to fix it ourselves.

$4.17 not including shipping. Sounds like the dealer is trying to screw you. Replace the relay and if you still have the issue it may be the motor..
