Hi there :). I have a polo mk 4. The rear wiper on my polo isn't working. It's had a new motor but still won't work, so i suspect the stalk or, god forbid the wiring somewhere. I've also checked the fuse which seems good. The washer on it works ok and the front ones are fine. Before i go and purchase a new switch, can anyone else who'd had a similar issue advise me at all please ? TIA Debz
