My Fabia rear wash freezes up very easily during cold weather and then doesnt work as the plastic pipe is popped off. Can anyone tell me how to remove the inside tailgate panel without damage so that I can repair it again. Does anyone know of a permanent cure?(the garage put a stronger clip on for me but still no joy) I dont want to waste money on mixing washer water with the blue stuff just in case its going to freeze.

permanent cure is to use screen wash

Couldn't tell you how to fix it as my dealer did it for me 4 years ago. Since then I've used screen wash
