| I've had this with both windows on both my MINI ONES, on my 03 ONE they fixed it by using lithium grease( sounds like something you would find on the uss enterprise). I took my current 04 ONE in for this a few months back and they said the windows were fine,NO THEY ARE NOT,they said that it was a little motor of some description in the drivers door that was making the noise(so why does the passenger window do it too)They replaced the little motor and its still squeaking. Not resolved. |
