raptor07GT Posted January 6, 2019 Posted January 6, 2019 hi all, having some issues with the windscreen washer jets. Drivers side is flowing like a fire hose but passenger side is pathetic Have cleaned the jets with a needle and can push needle right down the jets but just a dribble from passenger side took off the washer jet unit and blew through them, can blow fine checked there is water flowing to the wiper arm and there is If I'm getting water at the passenger arm then whats going wrong? Any idea for what I can try next? Quote
marzman Posted January 6, 2019 Posted January 6, 2019 There's a one way valve under the front windscreen cowling. These can get blocked up. Find that and remove/replace to see if it cures it. I swapped mine out for a biro lid once for a big improvement. Quote
raptor07GT Posted January 6, 2019 Author Posted January 6, 2019 would that one way valve cause the passenger side not to work while ok on the drivers side ? Quote
marzman Posted January 6, 2019 Posted January 6, 2019 (edited) I dont know it's been about 10 years since i did this on mine, but from memory, yes i think it could. Edited January 6, 2019 by marzman Quote
raptor07GT Posted January 6, 2019 Author Posted January 6, 2019 thinking about this, I've been a bit of a div! This afternoon I should have swapped over the passenger / drivers side jet housings and seen if the issue followed the washer units or remained on the passenger side. That'll need to wait now til next daylight working which wont be this weekend as car away to get electrical issue investigated. Stupid cars Quote

raptor07GT Posted January 7, 2019 Author Posted January 7, 2019 ha, I actually saw that video before I went to Halfords but because my drivers side jets will wash the entire car I assumed that wasn't the issue... I'll get the car back a week on Saturday(next time I'll have daylight) so I will have a good look at it and trace the tubing. I'm steeling myself for pulling out all the trim in the windscreen cowl just to get to the tubing I'll also have a hose joiner too Quote
D350z Posted January 8, 2019 Posted January 8, 2019 I had the same issue. I did the pin push thing and I thought I'd fixed it but I hadn't. The problem was the black (grey) clip on multi jet was full of black bits. I used blue tack to cover the little jets except the end one and I used another bit of blue tack to help seal the nozzle of a compressed air can on the end. I gave it a blast and loads of flakes of black stuff came out. A bit like small pieces of rubber. I then re clipped on the black jets to the wiper arm, connected the t piece and it now works like a charm. Quote
Keyser Posted January 8, 2019 Posted January 8, 2019 Is it possible the drivers side jet is worn and allowing to much water out, there is only so much water under so much pressure, as water takes the path of least resistance and the hole in the drivers side is to big all the water comes out there and non goes to the passenger side. Simple test block the drivers side and try the washers, may just need a new drivers side jet Quote
raptor07GT Posted January 8, 2019 Author Posted January 8, 2019 ^^ both very good points. I shall get some bits together and have a crack next time I have the car at the weekend. Cheers guys Quote
