Paul - Used US currency only, non-sequentially numbered. I manufacture a variant for use on non-ABS discs also - slightly cheaper.

adiaw83 - it's worth a try - $4 for the slider is not a big investment if it's something else. If it's the motor, try a regulator/motor assembly from the local MB wrecker - s/b much cheaper and the rear windows usually get very little use. I confess I did have to spring $17 for that small ball peen hammer - never did own one. Any excuse for a new tool....

Thanks both for your kind words.

Thomas.
