Repair Manual

BMW Cruise Control Actuator. This actuator was used on several BMW models from October 1985 through May 1999. The chart below may be used to cross reference the usage of the actuator. The cruise control actuator will seem to work only intermittently or partially when a tooth is broken in the gear driving the control belt drum. This is because the control unit will attempt to operate the actuator, but gets inconsistent feedback from the potentiometer when the drive encounters the broken tooth. The cruise control actuator is enclosed in a two part plastic housing. The throttle control cable protrudes through a fixture on the top half. A round male electrical connector for the control cable is also located on the top half.

Installation instructions:
Step 1: Raise the entire front of the car and protect it from the stands of Jack. Never work in the car supported only by the hydraulic floor Jack. Check your owner manual for the correct affixing of the stands jacks floor and Jack. If you live in an area where rust is the problem of liberal use of fluid penetrating it will be necessary and may increase the difficult installation. If you have any problems, please contact your worker.
