Suggested Remedy
Verify control station, wire harness and all cables are
securely connected. Clean if necessary.
Verify S1 & S2 coils (passenger's side slide box
retract and extend) and S9 & S10 (driver's side slide
box retract and extend) are connected properly.
Diagnose the wire harness. Review all wire harness
schematics. If power is present, review the next step.
Verify that the coils are magnetizing. Position a screw-
driver inside of the coil. When the respective function is
activated, the screwdriver is drawn to the side of the coil.
If the coil is not drawn to the screwdriver, replace the
coil. If power is present, review the next step.
Determine a damaged cartridge valve by reversing the
driver's side and passenger's side cartridge valves.
Replace valve if necessary.
NOTE: Verify coils S3 & S4 for angle functions.
