VW Window Switch – Front Driver Side 1J3959857B – OE Supplier 1J3959857B

A Door Window Switch, or switch pack, provides driver and passenger control of window operation. These switches are a high use item and can be a common culprit in a window system related failure. Symptoms of a bad window switch include total failure of a window operation, as well as partial or intermittent failure, and failure of window to move in one direction but not the other. Modern switch packs can incorporate intelligent functions such as one touch raise or lowering actions as well as safety systems such as finger protection. If you have fitment questions before purchasing the correct window switch for your vehicle, our customer service department would be happy to assist you. Be sure to provide a VIN to guarantee proper fitment.
