New Holland combine aircon water leak

[ewald]

The aircon on the TX34 works fine, but after a few hours starts to drip water into the cab.
I have blown out the drain hoses but am now out of further ideas!

Was it raining?

Do you have a heater as well as aircon? If so, taste the dripping water, if sweet, its a leaking heater matrix. If not, then its from the a/c doing its job. Very high humidity last couple of days, probably the drain pipe is split/loose.

Where did you blow the drain hoses from? Top to bottom or bottom to top? Some drain pipes have a valve in them so nothing should go back up the pipe.

No heater, not raining.
I have disconnected the hoses in the cab roof and blown in both directions. Pipes seem sound

As @GmB says it's been high humidity and real hot the last couple of days. Could it be the evaporator freezing slightly and the water can't only escape via the cab? Just a thought.
