another mystery , the windshield fluid light come on in the dashboard ... the system is working fine , I mean its spraying and everything and I did not notice any leaks or cracks on the reservoir! any thoughts? thank you in advance

 

It may be time to take the reservoir out and clean it. Make sure the float is moving freely and the connectors are all secure.

Yeah, but you didn't say if washer fluid level was where it's supposed to be, so that sensor does not trip. Washer fluid light is normally tripped by low fluid level. So, like Salim said - stuck float - or, low fluid level. Or bad contact on sensor.
