Chaps.. your expert advice needed please.
After recently fixing the air conditioning (just in time for winter) it is now working rather too well. (I'll put up a separate post describing how this was achieved but you won't like it).
After a little motorway run to check the newly balanced front tyres were no longer causing a slight wobble (they weren't!) noticed that when sat on the driveway with engine running there was a sound of trickling water from behind the dash. With the hood up and my ear pressed to the fusebox - it was clearly coming from just below this area.
A quick Google search suggests the noise is probably water condensing on the evaporator; dripping off and then not draining away sufficiently quickly so forming a puddle and I'm guessing it is the blowers agitating it and making the trickling noise. Strange thing is there was an impressive puddle of water under the car so clearly some water is draining out.
Looking at this diagram of the system suggests there are 4 points at which the water is drained from the plastic housing for the heating and air con evaporator and two points where water drains out to the ground: (correct?).
Maybe one drain is clear and the other is blocked?
Does anyone know a way of clearing the drains without dismantling the front of the car? Very grateful for any expert help.
