Evening folks.
My MOT is due soon, and I had realised that I hadn't seen my headlight washers operating, or even rising from inside the bumper, so I set about investigating why last week. I know they are required to be functional for the MOT, where fitted, before anyone says they aren't needed :wink: I'm not concerned at this stage about the caps flying off at this stage.
The jets wouldn't even pop up, so I ordered a new pump, which I fitted this afternoon; the problem remained. Hoping to ascertain where the tee is, splitting the flow of water to each washer jet, I had a fish around inside the bumper (the undertray has had a small hole since purchase). Lo and behold, there was an incredibly rusty set of mole grips clamping the hose. I eventually got them off, unkinked the hose, and tested the washers a few times (I'm aware of the 1 in 5 headlight squirts per windscreen squirts).
The washer jets pop up on the first operation of the pump, go back down when the pump stops, and then they come back up again when the pump operates for a second time on the same pull of the stalk on the column.
I can't see water pi$$ing out of anywhere, although everything is still wet from disconnecting the old pump. If there were a leak however, I wouldn't expect the jets to rise from the bumper, as I believe the jets rise due to water pressure (backed up by the fact that they wouldn't rise with the mole grips preventing flow). There is definitely enough water in the reservoir.
My questions are as follows:
Does everyone else's jets rise twice for a single pull of the stalk? If so, is water expelled from the jets on each occasion?
Has anyone else encountered this problem? If not, any suggestions?
Any assistance would be much appreciated.
