Trouble Diagnoses
Symptom Possible cause Repair order
None of the power windows can
be operated using any switch.1. 40A fusible link and circuit
breaker-1.
2. Grounds
B18andB27.
3. Power window relay.
4. Open/short in power window
main switch circuit.1. Check 40A fusible link (letter
e,located in fuse
and fusible link box) and circuit breaker-1. Turn
ignition switch to“ON”position and verify battery
positive voltage is present at terminal

12of
power window main switch, and other switches as
follows.
2. Check grounds
B18andB27.
3. Check power window relay.
4. Check W/R wire between fuse block (J/B) and
power window main switch for open/short circuit.
Driver’s side power window can-
not be operated but other win-
dows can be operated.1. Driver’s side power window
regulator circuit.
2. Driver’s side power window
regulator.1. Check driver’s side power window regulator circuit
2. Check driver’s side power window regulator
One or more passenger power
windows cannot be operated.1. Power window switches (front
sub-switch, rear sub-switch
RH, rear sub-switch LH).
2. Power window regulators.
(Passenger side, rear LH,
rear LH.)
3. Power window main switch.
4. Power window circuit.1. Check power window switches (front sub-switch,
rear sub-switch RH, rear sub-switch LH)
2. Check power window regulators (front sub-switch,
rear sub-switch RH, rear sub-switch LH)
3. Check power window main switch
4-1. Check harnesses between power window main
switch and power window sub-switches for
open/short circuit.
4-2. Check harnesses between power window sub-
switches and power window regulators for open/
short circuit.
One or more passenger power
windows cannot be operated
using power window main switch
but can be operated by power
window sub-switches.1. Power window main switch. 1. Check power window main switch.
