Speed Control Will Not Turn Off

WITH OFF SWITCH

Turn ignition off. Unplug 10-pin connector from servo. While pressing OFF switch, measure resistance between servo harness connector pins No. 5 and 6. Rotate steering wheel through full range while making measurement. If resistance is between 2090 and 2310 ohms, replace servo. If resistance is not 2090-2310 ohms, replace switch. Retest system.
