In my car windscreen washing system did not work properly. Symptoms were poor pressure of liquid coming out from jets, sometimes normal. sometimes less than 50%, sometimes no liquid coming from them at all; although the pump was working.
I thought it may be some dirt in sprayers. I blew compressed air thorough jets and this did not bring me any significant results. I was sure then it must get the new pump as I did not notice any leaks from pipes, pump, connections.
Pump it self is very cheap, around 5 eu (not the original one!!!).
Below step by step how to replace pump and jets in Scenic MK2.
Brand new pump and
sprayers/jets.
You can easily access the pump by removing wheel on RHS,
mudguard and
bumper trim.
This is the best way to get to to the pump, unless you have very small hands and you will be able to maneuver them in tight area between washer bottle and bumper.
The pump is placed just across from the bottle. You may see it on inspection mirror.
I would advice you to open lid or remove washer bottle neck. It is hold by two hanger clips
Disconnect wire then pull pump out and drain remaining washer liquid, then remove white and black pipes
Cut about 10-15mm of pipes ends
Pour some water or washer liquid into white and black pipe and use compressor to blow the pipes. If you do not have compressor you may use spare wheel or go to petrol station...
Remove round seal from old pump and put it on the one
Connect pipes and then slide pump into washer bottle. Pour some liquid into bottle and check connections for leaks. If it is okey connect electric wire. Time for a test!
Thanks!
