Fiesta Airconditioning Water Spill

[tomrob]

Hi

The car is a 1994 Fiesta Ghia X (Posh eh!).

When we use the airconditioning it usually spills water out of the aircon unit and into the passenger/driver footwells after a short while. I've checked the tube that takes the water out through the bottom of the car and now it does "wet it's spot" everytime it's parked.

I think I've cleared out this pipe before and the effect comes back. So, I'm not confident that I've cleared the problem.

We use the unit with all the windows closed and re-circulate air switched on.

Any ideas please?
