Last weekend I finally took the time to remove my windshield washer level switch on my 99. I hate to admit this, but several years ago I removed that switch and apparently installed it backwards without knowing it. Ever since, my low level appears on the message center when I filled the reservoir every time I started it. After a while of use, the message didn't show up.
I replaced the reservoir tank on my 06 Suburban because I have a persistent leak (which I still have!) and was going to use the switch on the 99. But I checked it and mine was good. So I reinstalled it but rotated it 180 degrees. I added a bit of RTV.
I also painted my battery tray since it was pretty corroded. I had painted the battery tray on the 06 when I did that. I'm guessing the battery acid causes this rust.
Anyway, no more annoying low windshield washer fluid message!
Regarding the switch: I think it should have continuity normally when there's fluid in the tank. As the fluid drops, the float causes the continuity to break. I compared the 99 switch vs the 06 and they are a bit different, but operation is the same.
