When the plug on your blower switch is worn, melted, or corroded, the Standard Ignition switch connector S-687 is designed to replace it. This auxiliary blower switch connector, also listed as an HVAC blower motor connector, is a direct-fit replacement for the listed applications. These include the 1982-1985 and 1994-1995 Chevrolet Impala, 1984-1987 Buick Regal, 1985-1995 Chevrolet Astro, 1987-2005 Chevrolet Blazer, and 1988-1996 Chevrolet C1500 and K1500. See the Buyer's Guide tab for the full list of 123 applications.
The connector plugs into the auxiliary blower switch and carries current between the switch and the vehicle's wiring. Signs it may need replacing include a melted, discolored, or corroded housing or terminals, a loose fit on the switch, or a blower that works only intermittently. If the connector is the cause, this replaces it. Diagnose the circuit before replacing parts, because other components can produce similar symptoms.
