AC and defrost suddenly stopped working

About a week ago, what seemed like the blower motor made some odd clicking sounds during one short drive I took. I figured this was an isolated incident as it did not last. However, I noticed yesterday that the defroster was not working, and that the fans weren't blowing air at all.

The climatronic buttons all work, with the exception of the AC max or max defrost buttons. When those are pressed, their lights flash as if they were turning on, but quickly turn off and those functions don't work.

I pulled out the blower motor yesterday and when I flipped it upside down it leaked probably 1/4 cup of water. We recently had a few days where it dropped below freezing at night and got to above 50F during the day which made me wonder if the motor had froze during that period.

I also checked for and removed debris from under the plenum chamber cover.

My first thought is the blower motor is bad, but was wondering if it could also be a relay or the blower motor resistor? This problem is mostly outside my wheelhouse.

Thanks in advance for any help.
