Hi
I have a renault megan and I am having problems with washers, I can hear motor and washer is full, tubes not blocked, but no water coming out any out there that could help.
Either the nozzles that point at the screen are blocked - but both blocked is unlikely - there could be some soap sludge in the bottom of the washer bottle thats blocking things up here. Try the rear screen wash - if that is ok then the pump is usually ok.
