My CX9 is less than 3 years old but has 44K miles so I'm out of warranty.
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.

"..armature is open and rusted..."
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.

I learned my lesson...stick to Honda products
...even if they look like crp!
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.

The blower motor is a Denso assembly; it's sealed with no way to repair. Any armature assembly when ohmed out should have some impedence but this one shows open - as if the winding was broken. Got any ideas I'm not aware of?

NOTHING is truly sealed.
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...?
r u near Seattle..?

I purchased the front blower motor online from DealerDirectParts.com. Their cost was $465 vs. any Mazda dealer I talked to at $611 for the same part. I paid $12 shipping but saved $37 tax. I replaced the blower with the 3 Torx screws, plugged in the connector & everything is fine. A notice to those owners out there who hear a swishing/ water noise under the dash; turn off the AC, check for an evaporator drain hose blockage & don't let the water overflow into the blower motor assembly under the passenger's dashboard. If your passenger's side front mat is wet; you've already overflowed water into the motor assembly & it's just a matter of time before the unit goes. Let's hope Mazda has a recall for this problem so I can get my money back for the motor.

wouldn't this have been covered under warranty?

not, if he is out of warranty (time/mileage) or does not have an extended warranty.

Where does the evaporator drain hose exit the vehicle? Does anyone have the service repair manuals for the CX9 and does it similar to the Haynes manuals? Thanks
