So on the advice of the guy in the parts place I bought a new motor for my window yesterday. Bit dubious that that was the problem but if it worked I would have been happy. So coughed up the money and lo and behold it's not what I needed. So, I went back today and they don't take returns for electrical parts.
Nice wee scam going there.
It's brand new still in the box, front drivers side (are the 2 door ones the same?) It's the type with the multiplug on it - about the size of a scart cable.
Cost me ?145 +VAT. Anyone want to make me an offer and I can send it to you.
