Windows Do Not Operate

NOTE: Ensure lock switch is in "UNLOCK" position. If driver's window will go up and down, but not automatically, replace master door lock/power window switch assembly. Refer to Figure when performing all testing.
  1. Using a voltmeter, check voltage between ground and terminal "E" (Blue wire) of connector "A". If battery voltage is present, go to next step. If not, repair open circuit in circuit breaker No. 25.
  2. Using a voltmeter, check voltage between ground and terminal "D" (Blue/White wire) of connector "A". If battery voltage is present, go to next step. If not, replace master door lock/power window switch assembly.
  3. Using an ohmmeter, check resistance between ground and terminal "F" (Black wire) of connector "A". If no resistance is present, go to next step. If resistance is present, repair open circuit to ground.
  4. Using an ohmmeter, check resistance between ground and terminals "B" (Blue/Black wire), "D" (Yellow/Black wire), "E" (Tan/Black wire), "F" (Tan wire), "G" (Orange/Black wire) and "H" (Orange wire) of connector "B". If no resistance is present, go to next step. If resistance is present, replace master door lock/power window switch assembly.
  5. Move window switch to "UP" position. Using a voltmeter, check voltage between ground and left front window switch terminal "A" (Light Blue wire), connector "B". If battery voltage is present, go to next step. If not, replace master door lock/power window switch assembly.
  6. Move window switch to "DOWN" position. Using a voltmeter, check voltage between ground and left front window switch terminal "C" (Yellow wire), connector "B". If battery voltage is present, go to PASSENGER WINDOW SWITCH TEST NO. 1Β  . If not, replace master door lock/power window switch assembly.
