Need help identifying fuse location for Pwr windows. Drivers side, front and rear work. Passenger side Front and rear do not work. I took apart the driver door and took apart the window controller and cleaned the contacts so I know that the controller works. (the pwr window lock for the windows is operable). I checked the fuses behind the coin holder and also the fuses in the engine compartment next to the battery. No indication of a blown fuse, but none of the fuses are labeled pwr windows. Any help would be appreciated . Thanx

I assume that your power door locks operate normally. If so, any one of the following may be a problem. I put the most likely problem point first in the following list:

1. Power Window Master Switch (driver door),

2. Individual Window Switches (each door)

3. GAUGE fuse in Junction Block 1/Rear side – Junction Block 1 is under dash, left of steering column

4. Damaged Wiring Harness

5. POWER M fuse in Junction Block 1/Rear side

6. Power Main Relay in Junction Block 1/Front side

7. Ignition Switch


==========================
Since the power Window Master Switch on the driver's door is the only one of the above that I believe can separately cause a problem with some windows and not others, I would test that first. You have cleaned the contacts on this switch, so that eliminates that possiblity, but I think you should check switch function as outlined below.

The fuses would most likely affect all the windows, but nothing is impossible.

==========================
To test Power Window Master Switch:
Gain access to the switch plug by removing the connector. With the notch upward, there should be 8 contacts on the bottom and six contacts on the top next to the notch. These contacts are numbered 6 5 4 3 2 1 on the top set, left to right (notch between 3 and 4), and numbered 14 13 12 11 10 9 8 7 on the bottom set, also left to right as written.

With an ohm meter, check the listed contacts for continuity in the following switch positions: If continuity is not as specified, replace the master switch.

(Since you are having trouble with passenger side windows, those are obviously the ones on which to concentrate.)

=====
Front Driver’s Switch
Switch Position: UP
6-7-8 and 1-2-13 continuity

Switch Position: OFF
1-2-6-13 continuity

Switch Position: DOWN
1-2-6 and 7-8-13 continuity
=====
Front Passenger’s Switch
Switch Position: UP
7-8-12 continuity

Switch position: UP and Window Lock ON
1-2-5 and 7-8-12 continuity

Switch position: OFF
5-12 continuity

Switch position: OFF and Window Lock ON
1-2-5-12 continuity

Switch position: DOWN
5-7-8 continuity

Switch position: DOWN and Window Lock ON
5-7-8 and 1-2-12 continuity
=====
Rear Left Switch
Switch Position: UP
7-8-10 continuity

Switch position: UP and Window Lock ON
1-2-9 and 7-8-10 continuity

Switch position: OFF
9-10 continuity

Switch position: OFF and Window Lock ON
1-2-9-10 continuity

Switch position: DOWN
7-8-9 continuity

Switch position: DOWN and Window Lock ON
7-8-9 and 1-2-10 continuity

=====
Rear Right Switch
Switch Position: UP
7-8-11 continuity

Switch position: UP and Window Lock ON
1-2-14 and 7-8-11 continuity

Switch position: OFF
11-14 continuity

Switch position: OFF and Window Lock ON
1-2-11-14 continuity

Switch position: DOWN
7-8-14 continuity

Switch position: DOWN and Window Lock ON
7-8-14 and 1-2-11 continuity

==========================
To test individual window switches:
Test contacts with ohm meter for continuity
Orient switch so that blank position is up. Contacts are numbered 2 1 (left to right) in upper row with the blank position between them. Contacts are numbered 5 4 3 in bottom row (left to right).

Continuity should exist between the following contacts in the switch positions stated:
UP: 1-5 and 3-4
OFF: 1-2 and 3-4
DOWN: 1-2 and 4-5
==========================
To test Power Main Relay:
Remove the Power Main Relay and place it so that all contacts are horizontal except one. The only vertical contact is to the right as you look at the relay. With an Ohm meter, check continuity. Continuity should exist between top and bottom pin. Apply battery voltage between top and bottom pins. Continuity should then exist between the other two pins.

To test the wiring harness, at least one of the contacts on the harness at each individual door switch should have battery voltage when the ignition switch is on and the window lock on the main switch is off.

I am having a similar problem. The right rear power window only goes down if you use the switch at that door. If you press up at that switch, the motor only gets 12V+ to the green wire, but no negative to the red wire. The Master switch at the door doesn't work at all. That only gives 12V+ in the up position, and nothing in the down position. What would cause this?
