Error Code 02 (Blend Door Problem)
WARNING: This page is about a different car, the 1992 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
- Unplug both control panel connectors. Check blend door actuator movement. Turn ignition on, with engine off.
- On 8-pin connector, attach a jumper wire from Black wire to Dark Blue/Light Green. See WIRING DIAGRAMS . Disconnect jumper wire from Dark Blue/Light Green wire and connect to Orange wire terminal. Blend door should move in both directions.
- If blend door actuator does not operate in both directions, proceed to next step. If actuator operates in both directions, plug in control panel connectors and retest system. See EATC SYSTEM FUNCTIONAL TEST . If test is successful (no Code 02), end test.
- If blend door actuator did not move in step 3), check blend door feedback potentiometer. Turn ignition off. Measure resistance between specified wire terminals on 12-pin control panel connector. See BLEND DOOR FEEDBACK POTENTIOMETER TEST table.
- If resistances in step 4) are okay, replace control panel. Check system function using EATC SYSTEM FUNCTIONAL TEST . If resistances were NOT correct, go to next step.
- Unplug both control panel connectors and blend door actuator connector. Check wiring between control panel and blend door actuator for continuity and short circuits. See WIRING DIAGRAMS .
- If continuity checks are NOT okay in step 6), repair or replace wiring harness. If continuity checks are okay, replace blend door actuator. Retest system. See EATC SYSTEM FUNCTIONAL TEST .
