Hey guys i got a 93 850 (non turbo) 4 door sedan. Been having problems lately ever since i changed the washer pump. I can hear the pump running but no fluid is coming out of the nozzles. I had to re-route the hoses since my headlight wiper blades are off and i don't want a puddle of washer fluid on my driveway. Right now i have a hose coming out of the pump to the inline check valve. from there it goes directly to the nozzles under the hood. Sometime it works and then sometimes it doesn't. Any clues on what it can be? There is washer fluid in the tank but i'm still confused on what the problem could be. Any thoughts would be greatly appreciated.

Thanks

 

Also if anyone has a diagram of the system that would be great too

 

The check valve is mostly likely bad. Bypass it and connect one of your spray nozzles, if washer fluid comes out replace the check valve. If no washer fluid then I'm stumped.

 

Yep, Most likely it is the anti-drain back check valve. On our 95 it was under the sound deadening pad on the hood.
