1. CHECK WINDOW LOCK SWITCH  .

   Check the window lock switch.

   Is the window lock switch OFF?

   Yes  : Go to  2.

   No  : Turn the window lock switch to OFF and operate.

2. CHECK REAR POWER WINDOW SWITCH  .

   Perform unit inspection of rear power window switch. Ref. to GLASS/WINDOWS/MIRRORS>POWER WINDOW CONTROL SWITCH>INSPECTION

   Is the rear power window switch OK?

   Yes  : Go to  3.

   No  : Replace the rear power window switch. Ref. to GLASS/WINDOWS/MIRRORS>POWER WINDOW CONTROL SWITCH

3. CHECK POWER SUPPLY CIRCUIT (OPEN)  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the rear power window switch connector.
   3. Turn the ignition switch to ON.
   4. Using a tester, measure the voltage between the rear power window switch connector and chassis ground.

      Connector & terminal 

      (Dr31) No. 3 (+) - Chassis ground (-):

   Is the voltage 10 - 15 V?

   Yes  : Go to  4.

   No  : Repair the power supply circuit.

4. CHECK HARNESS (OPEN CIRCUIT)  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the power window main switch connector.
   3. Using a tester, measure the resistance between the power window main switch connector and rear power window switch connector.

      Connector & terminal 

      (Dr31) No. 1 - (Df34) No. 1:

      (Dr31) No. 5 - (Df34) No. 2:

   Is the resistance less than 1 Ω?

   Yes  : Go to  5.

   No  : Repair the open circuit of harness between the power window main switch connector and the rear power window switch connector.

5. CHECK HARNESS (OPEN CIRCUIT)  .
   1. Disconnect the rear regulator & motor assembly connector.
   2. Using a tester, measure the resistance between the rear power window switch connector and the rear regulator & motor assembly connector.

      Connector & terminal 

      (Dr31) No. 2 - (Dr41) No. 2:

      (Dr31) No. 4 - (Dr41) No. 1:

   Is the resistance less than 1 Ω?

   Yes  : Perform unit inspection of the rear regulator & motor assembly. Ref. to GLASS/WINDOWS/MIRRORS>REAR REGULATOR AND MOTOR ASSEMBLY>INSPECTION

   No  : Repair the open circuit of harness between the rear power window switch connector and the rear regulator & motor assembly connector.
