As I understand it, the drain hoses are at each end of one common tray under the evaporator. I used this method, which I assume you're trying:

It worked easily for me.
BUT the Bentley manual, without a detailed explanation, says each hose can be removed by pulling it up out of the central tunnel. The large orange grommet (plugs into side of console) is an integral part of the hose.
If you try this, I'd like to see a report...theoretically the hose simple feeds back into place, then grommet plugs into hole with it's double lip.
WARNING : I've never tried this, but could be an easy fix...taking the hose out to clean it.

Just blowing compressed will open them but very likely they will not fully clean. I get a bit of silicone on them as well in an attempt to keep from sticking again.
It's a little tricky getting them properly seated again but with a small screwdriver its relatively easy to pop them into place again.
I am trying a preventive action once a year in setting the blower to full and shutting down all the air outlets, not sure it helps yet but we will see if it holds longer then before.

For those without access to compressed air, try using the compressed air cartridge from a bike tire inflation kit. Most bike shops have this and they are not expensive. Used this method on my car and it worked well. The orange A/C drains are flexible enough to fit over the top of the mouth of the cartridge making it leak resistant.
