Hiya, having a bit of a problem with my windows tipping as you wind them up (I think they tip forward). This makes them really hard to wind and I've stuffed my regulators over time (getting new ones soon). What is it that make them tip? Is it the plastic things that go in the runners or the scissor mechnism the regs use to raise the window? What can I do to fix this, or what do I have to replace? Any info would be much appreciated. Cheers, Chris.
