I'm troubleshooting a nonfunctioning rear window nozzle. The pump works, so my next step is to undo the hose attached at the nozzle end, and see if I can get water to flow. That'll basically tell me that the line is clear, not kinked, and that the nozzle is likely clogged or just plain broken.

Any wagon owners do this yet? Anything I should be aware of prior to getting to work? I'm told that there is a small screw holding the nozzle in place. My plan is to unscrew the nozzle, and hopefully pull it out enough so that I can remove the line from outside of the rear door frame (assuming enough line slack is there...) Make sense? Possible? Beuller?
