You need to begin by testing the switch with an ohmmeter. Here is the procedure below:
Switch Test Procedure
Seat Track Test Procedure
Following are tests that will help to diagnose the hard wired components and circuits of the power seat system. However, if the vehicle is also equipped with the optional memory system, these tests may not prove conclusive in the diagnosis of the driver side power seat. In order to obtain conclusive testing of the driver side power seat with the memory system option, the Programmable Communications Interface (PCI) data bus network and all of the electronic modules that provide inputs to, or receive outputs from the memory system components must be checked.The most reliable, efficient, and accurate means to diagnose the driver side power seat with the memory system option requires the use of a DRB scan tool and the proper Diagnostic Procedures. The DRB scan tool can provide confirmation that the PCI data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus, and that the memory system is receiving the proper hard wired inputs and relaying the proper hard wired outputs to perform its driver side power seat functions.Actuate the power seat switch to move all three power seat track adjusters in each direction. The power seat track adjusters should move in each of the selected directions. If a power seat track adjuster fails to operate in only one direction, move the adjuster a short distance in the opposite direction and test again to be certain that the adjuster is not at its travel limit. If the power seat track adjuster still fails to operate in only one direction, refer to Power Seat Switch Diagnosis and Testing in this group. If the power seat track adjuster fails to operate in more than one direction, perform the following tests. For complete circuit diagrams, refer to Wiring Diagrams.
