Recently the passenger side of front window spray outlet stopped working. The output on the drivers side is working but the power seems to be reduced with the spray only reaching three inches up the window (previously it would have sprayed up to 10 inches up the window).
The holes don't look to be blocked although I haven't yet tried poking then with a pin.
The spray for the back window is working fine.
I've never had this issue before and would appreciate any suggestions on any check which should be done - hopefully it's something easy (and cheap) to fix.
In case it's of help. The car is a 2006 TDI Sport.
