My windshield washer fluid pump abruptly stopped working two weeks ago on my ‘93 Mazda. I replaced the pump but it still doesn’t work. The only relative fuse I see is labeled windshield wiper but the wiper blades work fine. I couldn’t find any loose wires or obstruction in the tubing. There’s no fluid in the tubing. Got any ideas? Thanks.

 

Check for power & earth to the pump while someone squirts the wiper stalk.
