[Rhythmic]

My 2000 Grand Prix GTP has 140,000 miles on it. I have replaced 6 power window motors/regulators so far. Two doors have had the motor/regulator replaced once, two have been replaced twice. Pontiac went ahead and reimbersed me back for #5 (at 100,000 miles) when I complained, but refused to do so for #6.

Is this a common failure? I seem to go through these rather regularly.
