2010 Mazda3 blower issue

Hello all,

Need some help. My blower resistor keeps failing. I had 3 aftermarket and all failed either immediately or right away. Air flow on speed 4 is still pretty weak like not enough to feel it in my face but if I get close with hands I feel it.

Does this mean my blower motor is failing?
If so should I go OEM or aftermarket?
Also for the resistor , is it better OEM?

I'm gonna do an amperage test on the motor too.

Please let me know, thanks.
 
Check to see if anything has collected (or been deposited) in the fan, causing spinning to be restricted.
 
Electrical OEM parts are always better.

But it sounds like you have a short somewhere. So yeah, if you can, test the motor.
 
I hear as well those card type resistors can fail very fast if you dont install them inside. I plan on trying one more time. Seems like my first one was defective
