Check 2 The control switch, located in the driver's door panel, has a selector portion which sends voltage to the left or right side Listen carefully for the sound of the electric motors running in the mirrors. If the motors can be heard but the mirror glass doesn't move, there's probably a prob- If the mirrors don't operate and no sound comes from the mirrors, check the If the fuses are OK, remove the door trim panel (see Chapter 11). Turn the ignition switch ON and check for battery voltage at the mirror switch electri- in the wiring between the fuse panel and the switch and repair the circuit (see Section 31). Note: It's common for wires to break in the portion of the harness between the body and If voltage is present, connect a jumper wire from the BLACK wire terminal to a good 26 Power door lock system - description and check General description 1 Power door lock systems are operated by bi-directional solenoids located in each Check Refer to illustration 26.5 Check the fuses (see Section 3). 3 Operate the door lock switches in both directions (Lock and Unlock) with the ignition If there's no click, check for voltage at the switches. If no voltage is present, check If voltage is present but no click is heard, remove the door trim panel (see Chap- With the ignition ON (engine OFF), use a voltmeter to check for battery voltage to the terminal. Repair the wiring if voltage is not present. If the switch is OK and voltage is pre- sent but the solenoid still doesn't click, check the wiring between the switch and solenoid continuity. Using a voltmeter, check for battery voltage at the solenoid electrical connector; operate the lock switch. One of the wires should have voltage in the Lock position; the latch assembly (see Chapter 11). If the inop- erative solenoid isn't receiving voltage, check 27 Power window system - description, check and window motor replacement General description 1 The power window system consists of the circuit breaker, control switches, the |
