Just realized today that something is clogged with my AC. I just had my microfilters replaced and they still look clean and clear.

When I turn up the fan, it sounds like the air is running through a bucket of water. I also get water blowing out of my vents. If I turn sharp down the road, I can hear water sloshing behind the dash. I believe something to do with the drainage is clogged. Any ideas on where to look or what to do to clear things up?

Most likely a/c drain exiting under car is plugged up. Need to get cleaned out. But first chck to see if drains under microfilter are clear, a lot easier to check under hood, for leaves etc.

 

I have the same problem. This just started this week. Anyone with any idea as to what to do? I checked under the hood to see if anything was clogged and it's all clear.
thanks

 

It's either a blocked water drain for the AC compressor, or the heater matrix has blown. The first is cheap to fix the second expensive because you have to remove the whole dashboard to get to the matrix. You should have it checked by an indi or BMW.

 

Had this same issue. Unplugged the drain behind the passenger front wheel located behind the plastic wheel well protector. Didnt help. Put the car on a lift, removed both under car protection panels that cover the transmission and oil pan.Unplugged both drains that are located on each side of the transmission releasing lots of water. Both rubber bug and debri flappers were not opening. Cleaned them both out and cut a V with wire cutters in the bottom of the rubber to drain the water if it ever sticks again.
