For heat control on 123 300D 300CD 300DD 126 300SD 300SDL 107 380SL 560SL 1981-1991. Good used mono-valve switch solenoid. When this goes bad the valve will not operate and if it shorts and gets overheated then a new valve will not fit into the solenoid housing. This solenoid has been power tested and is working. We recommend you purchase a new mono valve unless yours is in excellent crack free condition.
Fits 1981 to 1991 models of the above chassis ONLY
