Re: 1998 grand voyager heater control problems
The blower motor is probably caused by the resister pack. 9 times out of 10 the resister is what causes that. The following post will have info about the flashing lights.

Re: 1998 grand voyager heater control problems
During the Actuator calibration, diagnostics are performed on the actuators and evaporator temperature Fin Sensor. Once diagnostics are completed the REAR WIPER and INTERMITTENT LED's will flash to indicate either a successful calibration or the appropriate fail code(s) At this time manual testing of the Blend, Mode and Driver (if equipped) potentiometers can be performed. If a failure is detected during Diagnostics a fault will be set in the control. When Ignition is cycled OFF and then ON or Diagnostics is aborted, the REAR WIPER and INTERMITTENT LED's will flash simultaneously showing that a failure has occurred. The control will not indicate the fail code, but only that a failure had occurred during the last diagnostics test. The only way to clear the failure codes is repeat the Calibration Diagnostic and Cooldown test, after all repairs are completed.
CALIBRATION/COOLDOWN LED DISPLAY CODES LED'S PASS/FAIL CORRECTIVE ACTION NO LED'S FLASHING-NORMAL OPERATION PASSED CALIBRATION, DIAGNOSTICS AND COOLDOWN NONE REAR WIPER AND INTERMITTENT LED'S FLASH SIMULTANEOUSLY FAILED CALIBRATION DIAGNOSTICS RUN CALIBRATION TEST A/C AND RECIRC LED'S FLASH SIMULTANEOUSLY FAILED COOLDOWN RUN COOLDOWN TEST REAR WIPER AND INTERMITTENT LED'S ARE FLASHING SIMULTANEOUSLY A/C AND RECIRC LED'S ARE FLASHING SIMULTANEOUSLY FAILED CALIBRATION, DIAGNOSTICS AND FAILED COOLDOWN TEST RUN CALIBRATION TEST CALIBRATION/DIAGNOSTICS TEST ENTRY To Start Tests: Set Blower motor ON HIGH Set Mode position to Panel Open all A/C outlets Set Temperature(s) to Cold Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light) RESULTS: All LED's will turn on for 5 Seconds Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing. Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit. After all tests have passed, Calibration Diagnostics and Cooldown can be run separately. RESULTS: All LED's will turn on for 5 Seconds Cooldown Test is running when A/C and RECIRC. are alternately flashing. If A/C and RECIRC. are flashing simultaneously, Cooldown has failed. |
