Wife comes home tells me the windshield washer is just dribbling fluid.. Pump motor is good, pull the line and I can't blow through it.. Put a garden hose on it.. and it's still just a dribble.. I try for about hour,. trying to flush the line.. Still I'm getting no where.. I don't want to pull the cowl.. so I just pull up the rubber seal, lift the cowl enough to pull the line up and see what looks to be a small filter right next to the first spay nozzle.. It's not a filter, but a check valve.. at any rate, it was clogged up.. It comes apart easy enough.. so you don't have to buy a new one.. and the best part, you don't have to pull the cowl off to get at it.. So if you've been putting off, fixing your washer.. no need to..
