Standard Ignition 4WD Switch P/N:TCA-45

Description

Keep your four-wheel-drive controls responding with the Standard Ignition 4WD Switch TCA-45 — the electrical switch that carries the four-wheel-drive selection signal within your truck's 4WD control circuit. It drops in as a direct-fit replacement for the listed applications: the 2003-2004 Cadillac Escalade, Escalade ESV, and Escalade EXT, the 2003-2004 Chevrolet Tahoe, the 2003-2004 GMC Yukon, and the 2003-2005 GMC Yukon XL 1500.

Job it does: serves as the switch in the four-wheel-drive circuit, opening or completing the electrical path used to signal the 4WD system.
Signs it may need replacing: an erratic or non-working 4WD indicator, or trouble getting the four-wheel-drive system to engage or disengage — if a failed switch is the cause, this replaces it.
Direct-fit replacement: a direct-fit for the listed applications.

Because a 4WD symptom can have several causes, diagnose the circuit before replacing to confirm the switch is the fault. This listing is for the switch as described.

Interchange: Manufacturer part number TCA-45 (also TCA45).
