Door & Tailgate Locks: Description

NOTE: Also refer to General Motors Motor Actuated Door Locks in this section.

The automatic door lock system uses the conventional power door lock system, but to accomplish the automatic feature the following additional components are used: Electronic logic module, unlock relay, lock relay (Cadillac), motor lock actuator relay, back-up lamp switch (Buick), right front door lock key cylinder switch (Buick), drive switch (Cadillac) and a seat sensor switch (Cadillac).

The module is located behind the glove box on Eldorado and Riviera, and behind the right kick panel on all other models. Lock and unlock relays are taped to the module except the Cadillac lock relay which is located behind the left kick panel. All switches and relays are replaced as an assembly. The module consists of 2 components: the wiring harness/case and the printed circuit board.
