Description
Product Overview
The Dorman 901-059 is a precision‑engineered 4WD mode selector designed to replace the original switch in Chevrolet Blazer, S10, GMC Jimmy, Sonoma and Oldsmobile Bravada models from 1994‑1997. Constructed with a solid brass contact set and a rotary actuator, the unit offers two positions for 4‑wheel‑drive engagement and disengagement. It features an ON‑OFF operation mode, normally‑open contact type, and a plug‑in connector for straightforward wiring. The panel‑mount design (3″ x 3″ x 3″) fits directly into the factory opening, and the black finish blends with the vehicle interior. With an IP00 rating, the switch is intended for interior use where moisture exposure is minimal, and its screw terminals ensure a secure electrical connection.
Usage
This switch is ideal for owners of mid‑90s Chevrolet and GMC trucks who need to restore or upgrade their four‑wheel‑drive system. Whether the original switch has failed due to fatigue or corrosion, the Dorman replacement provides a reliable, factory‑spec solution. Install it in the dashboard or center console where the original was located, connect the X‑10 protocol wiring, and the vehicle’s 4WD mode can be selected via a simple touch control. The unit is also suitable for off‑road enthusiasts who demand consistent performance in rugged conditions, as the brass contacts resist wear and maintain conductivity over thousands of cycles.
