Low pressure windscreen jets.
« on: December 12, 2023, 09:52:40 am »
Hi, I have an issue with my windscreen washer jets. They work… but initially when I press the stalk to operate the jets the pressure is so weak…. Then it bursts into life. I’ve removed both jets on the bonnet cleaned them and still the same issue. When I test the jets and look for any leaks under the bonnet I don’t see any. My xenon washer jets work no problem. Any common areas to check?

Thanks

I had a single weak jet and thought it was the jet, then thought the pump.........but it ended up being a cracked hose at the bend below the left bonnet hinge.

Replaced the pipe and full pressure returned

Thanks for the reply….I’ll have another look. Do you have a part number for the pipe?

I’ve purchased a repair kit for the hose at the bonnet hinge. I’ll give this a go and report back. Thanks again for the replies and information.
