Audi Window Regulator Rear Left (S4 A4 Quattro A4 RS4) - Genuine Audi 8H0839461A

Part number 8H0839461A is a brand new, unused Genuine Audi/Volkswagen window regulator.

Your Window Regulator is what raises and lowers your window (with some help from your window motor if you have power windows). If your window is having difficulty going up and down, chances are it is the regulator that needs replacing and not the motor.

It’s important to check and maintain worn window guides, tracks, and seals. The majority of window regulator failures are a result of a lack of inner door maintenance. You'll find that some basic maintenance goes a long way to help keep your power window system in proper working order. In most cases the existing regulator and guide components have worn simultaneously and may provide satisfactory performance until the regulator eventually fails due to another part in the system failing because it is completely worn out. The life span of a new window regulator will be greatly shortened if your vehicle has worn, dry or dirty guides and tracks. The operation of your window must be carefully inspected before installing this part. Any worn components must be replaced prior to installing this regulator, make sure everything is serviced, cleaned, lubricated and adjusted to manufacturer's specs. It’s possible that warranty claims will be denied if these procedures are skipped.
