The driver's side window regulator on my 2006 Ford f150 has broken three times, I was able to get two replaced under warranty, but the third time happened this last month, I am replacing it today. I believe from my experience, and from thousands of forum entries citing the same thing, that Ford should recall this part. This part is going to cost me approximately $400. 00 to repair.
