Windshield washer fluid wasn't coming out. A seized washer fluid pump turned out to be the culprit.

This is from a Superb MKII but many cars use the same pump.

part number 1k5955651

I opened the pump by pulling the two halves apart. Only pulling gets the two halves apart, it can not be twisted.

The motor was very rusty and seized, that's why it didn't work.

With pliers I got the rotor turning, then powered the motor with a 12V battery inside a glass with distilled water to clean it, worked well, dried it, oiled bearings, I packed silicone grease in the hole that the motor shaft goes into to drive the impeller because maybe from there the water leaked into the motor rusting it, not perfect but at least it is working now.

I had already ordered a replacement pump because I didn't believe the old one could be repaired or opened, and only after that I managed to open the pump and repair it, well I will use the old one as it works now and leave the new for spare.

The pump I bought was advertised for BMW 67126934159, it was cheaper than a pump with the VW part number but it seems to be the same.

You have a very "can do" attitude. 👍

I wouldn't have looked at that and thought "yeah that may be repairable". 🙂

I replaced one on a Vauxhall something-or-other for one of my neighbours, and it was only about a dozen quid for aftermarket. Looked similar inside after post mortem dissection.
