Another simple repair job that seems to be the root cause for many of the dead washer nozzle problems on our 20+ year old cars.
Depending upon if you have the intensive washer system (what genius at Porsche dreamed that up) you can have up to 4 check valves in your washer system. I circled the one that failed on my car below and replaced it.

First I disconnected the part of the T valve that went right to the driver's side (left) nozzle then activated the washer and saw no water was going through that part of the valve but that the right nozzle sprayed. So you can disconnect bit by bit to figure out where the plug point is. Once I figured out the check valve was bad is when I ordered the new one.

How did you remove the hoses and valves from the clips that hold them in place? I can feel the hoses tucked up under the lip in front of the washers but I don't want to break anything by just pulling them out unless that's the right approach. Any help would be appreciated. Thanks.

My windscreen washer work perfectly but very little comes through the Intensive Washer system (IWS). Normally I would just not use the IWS but hate having things in the car that do not work.
