wiper / washer issues.....

[midnite]

well when i started my truck tonight it was working as per normal... but after stoping and getting supper i got back to the truck and hit the wipers to clear the snow but the washer fluid would go as soon as i turned the wipers on... and would continue as long as the wipers were going ... i tried pulling on the lever when i turn the wipers on cause pushing it is suposed to make the fluid go ...

so the issue is that i cant get just wipers without fluid till i ran out of fluid

any ideas what to look at first?

thanks
