ive just perchased myself a fiat punto and the electric pack needs a bit of attention the left front window wont work and i can hear the motor grinding as if there is a cog striped or something,ive striped down the door but cant figure out how to get the rest of it out,if someone would be kind enough to write me a step by step instruction i would much apreciate it.the other thing is that the central locking doesnt work off the key fob ive changed the battery and still nothing,any ideas.oh and how do i change the front locks?sorry for all these questions but if someone can answer them they will save me alot of cash that i havent got.cheers
