914 windscreen washer - how does it work?
 

Hello,

I want to change the original windscreen washer ssystem on my 1971 Porsche 914.
If I put an elecrical pump on to the system, how can I activate this?
Can I do this via the existing button on the dash, or do I have to make an extra circuit to let the pump go when needed?
Thanks in advance for Your Answer,

I cannot remember the exact system used in 1970/71, but assume it had a water valve like the later cars. I made a switch housing and used a small switch to replace the valve. The switch activates a relay that activates the pump. A special disc I made replaces the air hose connection on the tank cap so that the cap is vented but relatively sealed. The pumps, similar to the 914/6, 911 & 928 are readily available.
