DEEP AC DRAIN CLOG?

We received some heavy rain and i had water leaking under the dash. It also seemed my fan was not able to put out as much as it normally would.

Is this a sign of ac drain clog? I inspected the drain and there was no clog. Could it be higher up in the fire wall? If I have a deeper clog (in firewall) what is best way to unclog?

 

Pull out your cabin air filter. If it is wet, then you had some crazy rain that made it into where the fan pulls fresh air from. Its under the plastic panel under the wiper arms by the base of the windshield. Check out this thread https://www.tacomaworld.com/threads/water-thru-cabin-air-intake-my-solution.88655/
