Detailed Description

Standard Ignition CBS-1105 is engineered for service replacement where the original multifunction switch has worn contacts, intermittent operation, or failed high-beam and wiper controls. Copper alloy conductors are used to support strong electrical conductivity with low resistive loss, and each unit is tested for mechanical and electrical switching performance before release. This part cross-references 1S10049 and DL6288 for the same application. Use CBS-1105 when servicing a 1998 Chevrolet Blazer, 1998 Chevrolet S10, 1998 GMC Jimmy, 1998 GMC Sonoma, or 1998 Oldsmobile Bravada with the listed equipment restrictions.
