Transfer Case Selector Switch – GM (19259313)

Transfer Case Selector Switch converts a physical condition into a signal the powertrain module acts on. The module compares that signal against an expected range at every start-up, so a failing unit is usually logged before it becomes a driveability complaint.

Replace the Case Selector Switch when the fault repeats with the harness already ruled out, when resistance drifts as the part heats up, or when a connector has corroded past cleaning. Swapping a sensor to chase a wiring fault is the most common wasted repair on these circuits.

For this Case Selector Switch the reference is 19259313, in our Sensors & Switches range. Compare it with the number on the part you are replacing rather than with a photograph.

Genuine GM supplied for this Case Selector Switch, with the engineering number unchanged from the factory reference stamped on the original.
