This problem just started on Sunday, I'm getting no air out any vents, doesn't matter the setting (a/c, vent, defrost, floor, automatic) or the fan speed. I ran the EATC self test and the only code that showed up was 051.
Where should I start in order to fix the problem? EATC o-ring repair, Blower Motor, blend door actuator?

051 EATC (Intermittent) Run-Time Fault = A/C Solar radiation sensor open circuit.
...whatever that means. I replaced my o-rings but had air coming out of the defrost only before the new o-rings. I believe the blend door is code 024.
Good luck. If it turns out you need o-rings, I have plenty.

No air at all is the BCM (mosty likely) or the blower itself.
Air out the defrost only is usually the EATC o-rings.

Where is the BCM (I'm assuming under the hood near the firewall) and what does it look like?

Near the heater hoses, square electrical connector.

So I tapped it and everything is working for now. I know this isn't a long term fix, but more of a means of diagnosing the problem. Will be ordering a new one tomorrow

I have repaired BCM's available. Need you old one back.
PM me.
BTW.. mine doesn't work when cold.
All that is required to fix it is re-flowing the solder.
Buying a new one is a complete waste of money

Plus 1 on that! Tapping mine worked for a year, heating up the solder joints inside, has been working for great now since.
