Wiring diagram for passenger door window switch

Do you know what a wiring diagram is ? How to use a DVOM - digital volt ohmmeter to test electrical circuits ? View wiring diagrams to see what all is involved in making the windows work . 05 Lexus probably has a electronic control module used to control windows . Does the passenger window only work from it's door switch ? Does the driver master switch open / close that window ?

Yes they run a wire loom that has wires that are not used in some models. One thing you need to check is the wire loom because it flexes every time the door opens and closes and wires can break .Also you may want to go to autozone website and make a free account, you can put in the year make and model and look for the free repair guides for wire diagrams.

Do the power door locks work for that door ? Does you vehicle have door courtesy lights , turn signals on the mirror ? If your vehicle has these other options an they work , you have power to the door . There is an electronic module inside the door ,called passenger door module ! where did you check for power at , the window switch ! These are computer controlled an you would only see a few volts when pushing the switch !

Your best bet is to take this to dealer or a ASE certified repair shop.

Try the switch on the pass side door. Otherwise you need to remove the drivers door panel, access the switch, print a wiring diagram and jump power to the window motor with a jumper wire.

All the wiring for all the windows flow through the master switch...both power and ground. So the problem is most likely a bad master switch or a broken wire in the hinge area of the driver's door. Get a wiring diagram and check for power and ground coming to the switch. If so, then the switch is most likely bad. Read this post http://ricksfreeautorepairadvice.com/window-goes-up-but-not-down/

Not following you completely.
When you say driver side passenger window, you mean the driver side rear window ?
The window motors get power thru a power window control unit and thru the driver master switch.
You'll need a shop manual with the wiring diagrams to track down the problem.

if u have ck all fuses & relays& tried the passenger switch & still nothing,,could have broken wire between door & door jam where the rubber boot is ,,u mite have to peel it back to see wires

you most likely have a power/ground/switch issue in the drivers door. the power for the other three doors must first travel through the switches in the driver door before it goes to the passengers. hence the reason why when somebody rolls down a passenger window and you push the up button on the driver door the window stops moving. the wires can break inside the rubber boot in the door jam. you can also have an internal problem with the driver door switch unit. you would need a wiring diagram to diagnose this concern.

The Master Switch may be bad. Thats the first thing to verify good or bad. It may be a big deal to find a wiring diagram and then verify where voltage is lost. All of the window power goes to the Master Switch,(through the lock out switch) then on to each window. Except for the right front window. The diagram is confusing, it does not appear that the lockout switch turns off the RF passenger window.

I removed all 3 switches from driver and passenger door, which is really easy with a flat head screw driver. took them completely apart, very carefully, with a small screwdriver out of a christmas cracker. put them back together again and 2 switches started working, so I put 1 in the drivers side and 1 in the passengers side so now my drivers door window opens and I lean over to open the passenger door. cool, no money spent...yet ;o)
