Default Headlight cleaning unit doesn't work.

Hi,
newbie here...

No washerfluid onto my headlights when I push the handle...
Windscreen washer works fine. Fluid in the resevoir.
I checked the fuse, no problem.
I don't hear any motor under the hood when I push the handle.

Any suggestions ?
If you all suggest trying a new motor-unit how difficult is it to replace it ?

Thanks!

Do you have a long list of problems

The pump is on the tank, which is located in the front right fender, so no easy access (welcome to 928 ownership ). Basically to check the pump you will have to remove the front right wheel and the plastic inside fender lining.

This thread has some pictures of the tank and pump: https://rennlist.com/forums/928-foru...mp-repair.html

if you get into the washer tank then you should also replace the fill spout and then remove the metal collar from the spout and the tank they will both rust.
A new spout is easy to remove the metal just dip the end into hot water then it slides out.
The tank will take some more doing as it will be well rusted, remove the tank from the car then throw a few handfuls of small stones into the tank with some simple green and a few cups of water and then shake the tank then rinse.
Usually the pumps can be be removed, taken apart, and cleaned, as they usually fill with rust from the removed collars

Of course its designed only to work when the headlights are actually up... assume that is the case?

you can also remove the fenderwell cover and pull the lower pump connector off raise the headlights attach a test light to the wires and see if power is getting to the pump

when removing old calcified rubber hoses that attach to plastic fittings,(anywhere on the car) always cut the rubber off the plastic, much less pain than buying replacement bottles/fittings after you have snapped off the plastic when trying to force the hose off.

to remove the washer lines, I have found that it is easier to use a lighter to heat the ends of the hoses YMMV
