CAR WASHERS

Weak pump, kinked hoses or clogged nozzles are the common causes of such problems.

Check hoses for kinking due to excessive bending or being compressed by other components.

Unplug hoses from nozzle and test the pressure, if it is good, ensure the nozzles are not clogged, usually by car wax.

thanks for your answers i have tried blowing the pipes through with high pressure air worked for one day then stop again taking it to a garage they had the washers working but the water barly hits the bottom of the windscreen the pump seems to be working ok the garage told me some cars suffer with this problem i will just have to suck it and see thanks anyway

If high pressure blasting of the hoses worked and then fail, there could be something inside the reservoir being sucked into the system and clogging it.
