Headlamp Washer Problem

[breezeblock]

Ok, hardly a major fault but I've just noticed my T reg GS300 has a fault with the headlamp washers. Whenever the button is pressed the water leaks out from underneath the passenge side headlight unit. I can't see exactly where but neither washers (driver and passenger side) work. I'm assuming there is a loose hose somewhere but where do I start to find it (without dismantling something I can't put back together)?

its an old post i know

When the piston is pulled back into the front bumper there is a small amount of water released through a small pipe on the jet unit, must be a non return valve in there I guess. on the driver side of my LS430 there is a leak which drains the washer reservoir overnight , the leak is coming from the unit (£132.00) to fix.
