Air Conditioner Noise & Leak?

[grumpstain]

Hey guys first time poster here. Just wanted to say that just popping off the drain hose and taking a shop vac to it for less than a second did the trick of loosening the blockage, then just drained it into a pot.

I know some people think it's annoying, but it's a very quick fix if you've got a shop vac or something with similar suction. Better than poking the blockage back up into the hose.

Not really adding anything new to the discussion, but I wanted to say "Thanks" to everyone for your instructions and photos on how to deal with this problem. I just experienced it for the first time today, and using the info in this thread, I believe I've corrected the problem. I unplugged the hose and ran a hanger into it, then the water flowed forth. I plugged the hose back in and a nice pool of water soon formed under my little Bayou Blue pal. We shall see how things progress in the next few days.

Again, thanks for the help!

looks like my kid has a problem with this. i instructed her not to use AC or fan and avoid sharp left turns. will try a wet vac after work.
scott's picture is very helpful: http://www.yarisworld.com/forums/sho...6&postcount=22

edit: the wet vac did nothing. i also probed and removed the rubber drain hose, no water or obstruction. where is the water coming from?

OK, i learned about this TSB 027-08:

the fix is a new cowl panel (55708-52170) "to help prevent debris from entering the HVAC unit".
but i have a filter already, why would debris enter AC?

anyhow, has anyone done that new cowl panel fix?

BTW, the lowest i can find is $158 (before S&H) for that large piece of plastic. is it worth?

With the filter in place the cowl update is really not necessary. It would just reduce the larger particulate captured by the filter.
