Air Inlet Actuator Inoperative

  1. Perform AIR DELIVERY SYSTEM CHECK . Go to next step.
  2. Turn ignition switch to ON position. Turn blower switch to medium-low (M1) position. Depress recirculation button. With DVOM negative lead connected to ground, backprobe A/C-heater control assembly connector terminal No. 4 (Dark Green wire). See WIRING DIAGRAMS . If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step  10.
  3. Disconnect air inlet door actuator connector. See Figure. Use a DVOM to measure voltage between air inlet door actuator connector terminal No. 6 (Dark Green wire) and ground. Ensure that recirculation button is depressed. If battery voltage is indicated, go to step  5. If battery voltage is not indicated, go to next step.
  4. Repair open in Dark Green wire between A/C-heater control assembly and air inlet door actuator connector. Go to AIR DELIVERY SYSTEM CHECK .
  5. Use a DVOM to measure voltage between air inlet door actuator connector terminal No. 5 (Brown wire) and ground. If battery voltage is indicated, go to step  7. If battery voltage is not indicated, go to next step.
  6. Repair open in Brown wire between air inlet door actuator connector and splice S243. Splice S243 is located approximately 1.5" (4 cm) from recirculation door actuator harness breakout, toward blower relay. Go to AIR DELIVERY SYSTEM CHECK .
  7. Use a DVOM to check continuity between air inlet door actuator connector terminal No. 7 (Black wire) and ground. If continuity is indicated, go to step  9. If continuity is not indicated, go to next step.
  8. Repair open in Black wire between air inlet door actuator connector and splice S244. Splice S244 is located approximately 3" (8 cm) from air inlet door actuator harness breakout, toward blower relay. Go to AIR DELIVERY SYSTEM CHECK .
  9. Remove air inlet door actuator and ensure that door moves freely and does not bind. If door is okay, replace air inlet actuator. Go to AIR DELIVERY SYSTEM CHECK .
  10. Disconnect A/C-heater control assembly 10-pin connector C3. Use a DVOM to measure voltage between ground and A/C-heater control assembly connector C3 terminal No. 5 (Brown wire). If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step  12.
  11. Replace A/C-heater control assembly. See A/C-HEATER CONTROL ASSEMBLY  under REMOVAL & INSTALLATION. Go to AIR DELIVERY SYSTEM CHECK .
  12. Repair open in Brown wire between A/C-heater control assembly and splice S268. Splice S268 is located approximately 2.5" (7 cm) into A/C-heater control assembly harness breakout. Go to AIR DELIVERY SYSTEM CHECK .
