Standard Ignition Ignition Switch P/N:US-136
Standard Motor Products
Standard Ignition US-297 ignition starter switch for the 1998-1999 Chevrolet C1500 and other vehicles sends battery power to the starter and ignition circuits when the key is turned. It is engineered specifically for GM vehicles.
A key that turns without cranking the engine, or accessory power that cuts out, can mean the ignition starter switch is worn, though a weak battery or a failing starter can also be the reason the engine won't crank.
It is listed for a wide range of Chevrolet, GMC and Cadillac models, led by the 1998-1999 Chevrolet K1500 and the 1998-1999 Chevrolet Tahoe. The 1998-1999 Chevrolet K1500 takes one switch.
