Standard Ignition 4WD Switch P/N:TCA-47
Replace a worn four-wheel-drive actuator switch on your GM truck or SUV with the Standard Ignition switch TCA-32. This 4WD switch, described by Standard Ignition as a four wheel drive actuator switch, is a direct-fit OE replacement for many vehicles, among them the 1995-1997 Chevrolet Blazer, 1994-1997 Chevrolet S10 and 1994-1997 GMC Jimmy. See the Buyer's Guide tab for the full list and engine details.
The switch works in the four-wheel-drive actuator circuit, helping the system and its 4WD indicator register when you shift in and out of four-wheel drive. A 4WD indicator light that won't come on or won't go out may mean the switch needs replacing. So can four-wheel drive that doesn't engage or disengage as expected. Wiring or the actuator itself can cause similar symptoms, so diagnose the cause first. If a failed Blazer switch on a 1995-1997 Chevrolet Blazer, or the switch on a 1994-1997 Chevrolet S10, is the cause, the TCA-32 replaces it.
