Can anyone tell me what's going on? > The rear washer on my 245 will spray the fluid for about 20 seconds then nothing even though the pump is buzzing away. If it sat for a while, I'd get the same thing: it would work, then quit again. I swapped the front pump in and no difference. I didn't think it could be a clog (I have always had one of those small filters on the inlet hose) but I took the nozzle off and tried again: still nothing. Then I tried blowing through the hose: couldn't!! Seemed like it would take some big psi's to do so. I can't imagine what could be blocked or causing this and how or why it would start working again. Thanks for any help.
