I don't know if this is an issue with all Rams in cold wet weather but with my 2017 Ram 2500 the squirters freeze up from snow settling down in the squirters or after a rain and the temps go below freezing. I tried all kinds of different fluids and it's the squirters. So long story short it's been snowing around here so the roads are a mess with salt and they froze up again making it a mess to see out the chalk white windshield. So a few days ago I tried using them after getting some engine heat to thaw then and nothing. I could hear the washer pump running every time but nothing came out. So the washer pump finally quit the other day so today I had a chance to check it out. Tried finding a fuse thinking it could have blown. No fuse. So I thought I fried the washer as this has been going on for over 7 years in winter. So I thought let me look online and see if there is any issues to resolve this after I replace the pump motor... So I read about how one guy says his motor stopped working and all he did was blow back through the line till he heard bubbles in the washer reservoir. So I went out after reading thinking what can it hurt, costs nothing and it's simple. Popped the hood open, saw the connector at the cowl, popped the hose off blew into it heard nothing then blew again and heard the bubbles in the tank. So I lowered the hood, hit the washer fluid then heard the pump instantly and it works fine again. So if you end up having this issue chances are this will work for you also...
