    3. Turn the ignition ON (II).
    4.  
    5. Lower the driver's window all the way down by pushing the driver's switch to the second detent (AUTO DOWN) when the window reaches the bottom, hold the driver's window switch in the AUTO DOWN position for 2 seconds.
    6.  
    7. Raise the driver's window all the way up without stopping by pulling the driver's switch to the second detent (AUTO UP) when the window reaches the top, hold the driver's window switch in the AUTO UP position for 2 seconds.
    8.  
    9. If the window does not work in AUTO, reset the power window control unit according to the above procedure again.

Testing



Battery Test

CAUTION
A battery can explode if you do not follow the proper procedure, causing serious injury to anyone nearby. Follow all procedures carefully and keep sparks and open flames away from the battery.

Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. If you don't have one of these computerized testers, follow this conventional test procedure:

  1. Be sure the temperature of the electrolyte is between 70°F (21°C) and 100°F (38°C).
  2.  
  3. Inspect the battery case for cracks or leaks:
    1. If the case is damaged, replace the battery. n
    2.  
    3. If the case looks OK, go to step 3.
    4.  

  4.  
  5. Check the indicator EYE:
    1. If the EYE indicates the battery is charged, go to step 4.
    2.  
    3. If the EYE indicates a low charge, go to step 7.
    4.  

  6.  
  7. Apply a 300 amp load for 15 seconds to remove the surface charge.
  8.  
  9. Wait 15 seconds, then apply a test load of 280 amps for 15 seconds.
  10.  
  11. Record battery voltage:
    1. If voltage is above 9.6 volts, the battery is OK. n
    2.  
    3. If voltage is below 9.6 volts, go to step 7.
    4.  

  12.  
  13. Charge the battery on High (40 amps) until the EYE shows the battery is charged, plus an additional 30 minutes. If the battery charge is very low, it may be necessary to bypass the charger's polarity protection circuitry:
    1. If the EYE indicates the battery is charged within three hours, the battery is OK. n
    2.  
    3. If the EYE indicates the battery is not charged within three hours, replace the battery. n
    4.

Starter Performance Test
  1. Disconnect the wires from the S terminal and the M terminal. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.
  2.  
  3. Make a connection as described below using as heavy a wire as possible (preferably equivalent to the wire used for the vehicle).
  4.  
  5. Connect the battery as shown. Be sure to disconnect the starter motor wire from the solenoid. If the starter pinion pops out, it is working properly.

  8.  
  9. Disconnect the starter battery from the starter body. If the pinion retracts immediately, it is working properly.
  10.  
  11. Clamp the starter firmly in a vise.

  12.  
  13. Connect the starter to the battery as described in the diagram below, and confirm that the motor starts and keeps rotating.
  14.  
  15. If the electric current and motor speed meet the specifications when the battery voltage is at 11.5 V for 2001-02 models or 11 V for 2003-06 models, the starter is working properly. Specifications:
    1. 2001-02 models: 80A or less (electric current), 2,600 rpm or more (motor-speed)
    2.  
    3. 2003-06 models: 80A or less (electric current), 1,180 rpm or more (motor-speed)
