2001 S Type Jaguar Sport windscreen washers don't work

it will be either blown fuse for windscreen washer or the motor for pumping water is stuffed which is common buy replacement from any auto store or direct from your vehicle manufacturer for original parts

Most likely the pump (motor) is gone and needs replacement. However, it is worth checking that fuse allocated to windscreen washer is intact. Furthermore, you may also need to check the wiring for flow of current at lever end (handle on the steering wheel) and wires connecting to pump on the water reservoir.

Hi, First check that you have wash liquid in tank. second make sure that it will not freeze by putting alcohol in your mix of water and soap. You can buy it already mixed at most service stations. Check pump for corosion on contacts.
Good luck.

If no noise is heard the pump is not working, this is most likely to be a blown fuse. check fuse under bonnet usually fuse number 2 which is 10 amp (red).

First I would start by looking for a broken line. It will be rather obvious as it will leak out on the ground after being actuated a few times.

not sure i can answer all your Q but it sounds to me like the pump is going and i would try to replace its cheap and easy to do,,i hope it works for you

try taking a pin and cleaning the holes on the squirters and if that does not work check the washer pump it is located on the washer fluid tank

The radiator tanks develope cracks in the base and leak under pressure, to replace remove plastic cover across body under windscreen to get access to tank then removal is easy you might have to remove plastic inside mudguard

remove the pump, there is a screen filter on the pump itself and it gets clogged very often.
