2012 Mazda 5 AC Blower not working

[MichaelWMoo]

2012 Mazda 5 AC Blower stopped working/blowing. Checked the relays, fuses and replaced the resistor and still not blowing. The blower looks almost impossible to replace. It would work of and on, then just stopped working completely. Any suggestions??

Can't find a video on how to replace it.

First check to see if there is B+ at the blower relay. If there is, then jumper the power side of the relay to see if the blower will spin that way.

I switched the relay and nothing changed

That only confirms that the relay is (probably) not bad. Without additional testing, you can't tell if it's the blower motor that's bad, or if the problem is something upstream from it (switch, wiring, connector, ...). You might find out that the blower is ok if you test it with direct battery power. However, if it doesn't spin with the relay jumpered, it's still possible that the blower is good, if the problem is actually with the blower ground.

I understand now
