washer fluid warning light on dash but container is full
 

Title says it all; just started today. Any/all help appreciated

level sensor is faulty or is stuck. if you dont mind checking it every now and then you can just remove the plug and the light will go out

I had the same problem on 3 of my 4 XJ's. The little float in the tank get saturated with crud and won't float anymore. You can either by a new one or do like JakeJeep said, Unplug it. That all I did. It only takes a second to check the level. You should be checking the levels on all of the fluids on a regular basis anyways, What's one more.

Thanks, that is what I was thinking but I was hoping if I could clean something easily, it would go away but like you say I am under the hood most of the time so no big deal. Thanks for the quick reply!
