Guide the rear left door glass up and down with the Dorman window regulator, part number 749-639, a power window regulator (regulator only) from Dorman - OE Solutions. It fits many vehicles, among them the 2004-2008 Audi S4, 2002-2010 Audi A4 and 2002-2010 Audi A4 Quattro. See the Buyer's Guide tab for the full list and engine details.
This Dorman OE Solutions window regulator is the mechanism inside the rear left door that raises and lowers the glass when the power window motor drives it. It is supplied as the regulator only, so the window motor is not included.
- Matched to the original: Dorman precision-engineered and extensively tested it to match the stock regulator's fit, function and performance on the listed applications.
- Cycle-tested: It was run through thousands of cycles in an actual vehicle door during testing.
- Engineered in the USA: It is backed by Dorman's long history in the automotive aftermarket.
- Direct fit: It is reverse-engineered to the original equipment shape and dimensions for a direct, seamless fit.
If a worn or broken regulator is the reason your rear left window drops, binds, travels crooked or grinds, this unit replaces it. The motor or switch can cause similar symptoms, so diagnose the cause before replacing parts.
