Checking flow and clearing clogs in your windshield washer
If you press the button for windshield juice and nothing comes out, you probably have a clogged windshield washer nozzle. Start your diagnosis by making sure there’s fluid in the reservoir. If so, check for fluid flow at the tee near the cowl (Photo 1). If that checks out, leave the tubing off the tee and clear out the nozzle with a compressed air gun (Photo 2). However, if you couldn’t get fluid flow at the tee, you probably need a new pump (see our article on “Windshield washer repair” ).
