Blower not working

[Niall]

Yes, tube all in tact. In fact it looks brand new under there!

"AC Drain" sounds important. Are we talking water or air drain? And what happens if it isn't there then?

Its a condensation drain but i honestly wouldn't worry too much. The main drain is under the evaporator so this little one on the blower motor is just for anything that passes that or comes in via the air intake under the scuttle.
