Heater unit leaking water

[craig1651]

Put a hose pipe down into the gully where the wiper mechanism is and turn it on hard pointing it to the passenger side and you will see water running
onto the heater matrix.

If you could get into the section under the cowl there is a duct that sits directly above the heater matrix, water runs into this when
leaking from the clips that the screws go into, seal up the clips screw things with mastic and refix the screws.

ill seal up my screws and clips but could water not get into the gully from the drivers side of the car anyway?

It can get into the gully both side, but there is 100% a duct above the heater matrix, do what I said with the
hose pipe you will be surprised.
