Power Window Switch

Any diagnosis of the Power Windows system should begin with the use of scan tool and the appropriate Diagnostic Service Manual. 

The hard wired inputs and outputs of the speed control system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the Local Interface Network (LIN) slave node integral and internal to the door control switch. The most reliable, efficient and accurate means to diagnose the LIN slave node operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
