Standard Ignition Ignition Switch P/N:US-136
Standard Motor Products
Standard Ignition US-588 ignition starter switch for the 1999 Chevrolet Silverado 1500 and other vehicles switches power to the starter and ignition circuits when you turn the key.
A failing ignition starter switch can show up as a no-crank or on-and-off starting, or as dash lights that flicker when you turn the key. A weak battery, for one, can look much the same, so these signs alone do not prove the switch is the problem.
US-588 is an ignition starter switch engineered for GM vehicles, including the 1999 Chevrolet Silverado 1500, the 1999 Chevrolet Silverado 2500 and the 1999 GMC Sierra 1500. A 1999 Chevrolet Silverado 2500 takes one switch.
