Both of the rear door WINDOW MOTOR Front door window lift motors use permanent type magnets. The B+ and ground applied at the motor terminal pins Refer to the appropriate wiring information. DIAGNOSIS AND TESTING - POWER WINDOWS WIRING VOLTAGE TEST The following wiring test determines whether or not voltage is continuous through the body harness to the front 1. Remove the power window switch and bezel (Refer to 8 - ELECTRICAL/POWER WINDOWS/POWER WINDOW SWITCH - REMOVAL). 2. Disconnect wire connector from back of power window switch. 3. Switch ignition to the ON position. 4. Connect the clip end of a 12 volt test light to Pin 14 of the window switch harness connector. Touch the test light probe to Pin 10. • If the test light illuminates, the wiring circuit between the battery and switch is OK. • If the lamp does not illuminate, first check fuse 13 in the Power Distribution Center (PDC). If fuse 13 is OK, Refer to the appropriate wiring information. POWER WINDOW MOTOR TEST If the power window motor is receiving proper current and ground and does not operate, proceed with motor test. 1. Remove front door trim panel as necessary to gain access to power window motor wire connector (Refer to 23 - BODY/DOOR - FRONT/TRIM PANEL - REMOVAL). 2. Disconnect power window motor wire connector from door harness. 3. Using two jumper wires, connect one to a battery (+) source and the other to a good ground (-). 4. Connect the Negative (-) jumper probe to one of the motor connector terminals. 5. Momentarily touch the Positive (+) jumper probe to the other motor connector terminal. When positive probe is connected the motor should rotate in one direction to either move window up or down. If 8N - 110 POWER WINDOWS KJ |
