It is under the glovebox area. Pull the hose off and be prepared to catch
some water if hose is indeed blocked.

I would use compressed air to blow the debris out of the hose.

Might try Miata.net garage section. Almost any question can be answered in
either the garage section or their forum.

I had a screeching sound on my 91A and it was the AC belt needed to be
tightened a bit.

Think one fan will run when coolant temp gets high enough and the other will
turn on with the air conditioning. I know this is documented in the
Miata.net garage section.
