Windshield washer refill light stays on even when I fill it.
Unplug the sensor in the bottle if the light goes out you have a bad sensor, if the light stays on you have a wiring problem in the sensor circuit.
If you use rain x washer fluid it leaves a film on sensor. I ran 1 gal regular fluid thru it then filed it 1/2 gal regular & about 6 oz dawn dish soap .dawn dish soap is a degreaser it cleaned tank & censor 2 weeks mine is still ok good luck Don't use Rain X fluid
10 years of running rain x in fords never had a problem ...first time i use it in my ram the level sensor bugs out
