See the "Vehicles it fits" section for the full list.
- Copper alloy conductors: used for strong electrical conductivity with low resistive losses.
- 100% tested: every switch is checked for both mechanical and electrical switching performance.
- Quality control throughout: Standard Ignition is a global manufacturer of original-equipment ignition products and oversees production from componentry to the finished part.
- Robust design: high-grade materials built for the demands of today's service professionals, backed by decades of research and development focused on what technicians need.
A worn blower switch can leave the fan dead on one or more settings. The blower may also cut in and out, or not respond when the knob is moved. A blower resistor, motor or wiring fault can cause similar signs, so diagnose the circuit before replacing parts. If the switch is the cause, HS-203 replaces it.
