find engine code for bad switch

Unfortunately, you will not have an Engine code for a bad switch. Leave this diagnosis and repair to your local Dealership as they have the trained technicians and proper diagnostic tools. Here is some insight on the systems you are concerned about. POWER LOCKS The instrument cluster locks or unlocks the doors when an actuation input signal from a door lock switch or Remote Keyless Entry (RKE) transmitter is received. The instrument cluster turns on the output drivers and provides a voltage level to the door lock motor for a specified time. All passenger doors can be locked or unlocked using a mechanical button mounted on the door trim panel. The drivers door can be locked or unlocked by using the key cylinder. . OUTSIDE REAR VIEW MIRROR The power operated rear view mirrors allow the driver to adjust both outside mirrors electrically from the driver side front seat position by operating a switch on the driver side front door trim panel. The power mirrors receive a non-switched battery feed through a fuse in the junction block so that the system will remain operational, regardless of the ignition switch position. POWER WINDOWS Vehicles equipped with certain options are equipped with an electronic door control module (also known as the Driver Door Module/DDM or Passenger Door Module/PDM) on both the driver and passenger front doors. Two distinct variations of these modules are used, one with receptacles for up to four wire harness connectors (1) and the other with receptacles for only two wire harness connectors (2). The base two-connector module is used on vehicles with express up and express down (also known as one touch) power windows without the optional memory system. One four-connector module is for vehicles with the express power windows and the memory system, but without turn signal and puddle lamps in the outside rear view mirrors. A second four-connector module is used for vehicles with the express power windows, the memory system and with turn signal and puddle lamps in the outside rear view mirrors. conventional diagnostic methods will not prove conclusive in the diagnosis of the door control module electronic controls or the communication between modules and other devices that provide some features of the power window, power mirror, memory, turn signal and courtesy lighting systems. The most reliable, efficient and accurate means to diagnose the door control modules or the electronic controls and communication related to system operation requires the use of a diagnostic scan tool.
