OK, I received my rebuilt regulator within days, but I was unable to get the car back to the shop until now.
The body shop installed it and all is well.
Labor cost me only $60.00. It took hours to take out since the window blocks the bolts. Rebuilt was $85 plus $8 shipping. Total = $153.
That is better than Acura's $850 quote for a new one. However, I did not get a loaner car, and 20 people did not ask me if I wanted coffee.
Now, if my financial advisor is correct, I can invest that savings of $700 and it will be worth something like $200,000,000 when I turn 100 years old. Maybe then I can afford a new regulator.
