Theories Requested

The ST’s windshield spray system is no longer working. It’s been in and out for some time requiring me to push the button like 500 times before it worked. Here are some facts to help us get some possible diagnoses.

- There is fluid in the reservoir

- The rear sprayer works fine.

- The wipers, which are automatically triggered when you spray, don’t turn on when I trigger it. This leads me to believe that it is an issue with the system than any specific part, hose or nozzle.


- The wipers still work on their own.

My personal theories are:

Rats have chewed a wire somewhere
I pierced a wire installing the lights
Some sensor/relay is borked somewhere
Lines are frozen
Nozzles are blocked by excessive waxing
