URL for the Ebay search

They look like aftermarket replacements for around 100 bucks. The regulators are 200 a piece from GMPARTS direct and $330 from the dealer.

I'm wondering if those are worth $100 or if anyone has tried aftermarket regulators and had any failures

just did one works awsome

There was a company on line that refurbished failed regulators. I understand the rebuild quality was better than oem.

I've used three of the Ebay ones (each on a different window). Each replacement regulator is holding up well, but it'* too soon to tell if they're going to break again. (the oldest one is only 1.5 years old)

sounds good. thanks to all that responded.
