The one pump powers both nozzels. (Actually one nozzel with two jets)
The problem is most likely the nozzel itself. It gets plugged up VERY easily. I've replaced mine 5 times untill I thought to change the hose from the washer pump to the nozzel as the rubber hose was deteriorating on the inside and causing the nozzel to plug up.
oh thats a good idea! replace that hose! yup thats next on my list! that and figure out why not washer fluid! hardly worked yesterday and not at all today. No sound from the pump when i push the button so I need to check for voltage at the tank and go from there. Thanks for hte good idea to replace that hose though too!
