Windscreen wiper's and washer's

[MISSY30]

Delphin's MOT is due and the washer's and wiper's don't work.

The washers just dribble a feeble amount on to the bottom of the screen, Do I need a new washer jet pump? And where will I find on the car?
I did think that there was water dripping down from under the dash on the drivers side after I'd tried to use the washer's, Is this possible?

Because I've been turning on the wipe/wash but it's not had any water on the screen it's broken the spline bit of the drivers side wiper. What part do I need to replace this?

Any help appreciated

does it only make a feeble spray when you pull the stalk towards you?

if so it'll be a leak from the main screenwash tank (LARGE one on RH front wing), or the piping there abouts.

if you push the stalk in (towards the steering column) then the spray should be delivered from the 'intensive wash ' reservoir (small one on RH front wing)

Leak from the dash-cant see how that could be washer related, unless there is a piece of piping running along the scuttle/bulknead panel

hope that helps.

ps the piping and white connectors are relatively cheap from the stealers

Its worth replacing the checkvalve that connects to the washer pipes. They regularly pack up with the result of getting little or no water through the jets. They are available from the main dealers and aren't expensive. The little hose clips attaching it are a b***h to remove and replace so be patient.

Thanks Guy's
If the check valve is the one in between the washer jets on the inside of the bonnet?
I had another look last night to see if I could spot the leak and had the bonnet up when I was trying the washer's and that bit was leaking, I've got another bonnet with that bit attached so I'll rob that and hopefully that will solve it.
I didn't know the wiper's were held on by bolts I thought they pushed on, Hopefully when I put the new wiper arms on if I do the bolt up tight they will be fixed.

Another thing I've always changed on my E30's are the nozzles themselves, always makes a huge difference, they always get clogged up with age, only a couple of Ԛ£Ã”šÃ‚£ from the dealers.
