Dimmer Control Module
- Remove top steering column cover to access turn signal multi-function switch. Speed control dimmer module is located on right back side of turn signal multi-function switch. Check all switch wire connectors for clean and tight connections.
- Remove screw attaching dimmer module to switch and remove module. Using an ohmmeter, check for continuity between dimmer module pins No. 1 and No. 3 and between pins No. 3 and No. 4. See Fig 1 Continuity should exist in both tests. If continuity does not exist in either or both tests, replace dimmer module. If continuity exists in both tests, inspect circuit No. V32 (Yellow/Red wire) from PCM terminal No. 5 to brake switch terminal No. 3 to dimmer module pin No. 4. See WIRING DIAGRAM . Repair Yellow/Red wire as necessary.
