WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the seat adjuster switch.
- Test for less than 5 Ω between the ground circuit terminal B and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the appropriate B+ circuit terminal listed below and ground:
- 6-way power seat terminal D
- 8-way power seat terminal E
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, test or replace the seat adjuster switch.
