Usually on that model of car, The switch is bad, and need to replace the switch. Get a jumper wire and by pass the switch. Also need to get a cam of silicone spray, and spary the window tracks. This will free the window up so that it will not put a strain on the switch. This will also burn the switch & motor up.

2000 Buick Park Ave-door panel buttons stopped working. What should I check? I am completely lost when it comes to cars and broke. Other 3 windows will work using their individual buttons but not with...

There is a rubber boot that goes from the body of the vehicle to the door , with that door open . There are wires inside that boot that supply B+ voltage an a ground an other wires . They break sometimes an they need to be repaired , soldered , connectors or what ever you can do or afford . First off you need to take the inside door panel off , an pull the switch an test for power an ground . There are videos on you tube showing how to do it . Videos on basic automotive electrical testing , how to read a wiring diagram . Go to free wiring diagrams .
Power Windows
The vehicle is equipped with power windows controlled by the door modules. The DDM receives a window switch request, over the SBI serial data, from either the passenger door module wired to the window switch pressed or from the driver door switch assembly. The DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation.
If the status information to permit window operation is correct, the DDM sends the command to the door module controlling the window to move the window as requested.
Windows Power and Ground
The windows are powered by discreet power and ground circuits. These circuits are in the same dedicated connector as the window motor drive circuits.


  1. Install a scan tool.
  2. Observe the power window switch parameters in the driver door module (DDM) data display, Inputs data, using the scan tool.
  3. Activate each power window switch.
Do all parameters change to the up, down, and for the front door window switches the express states?
Go to Step 10
Go to Step 3


Does the driver door window switch parameter indicate all four states (Idle, Up, Down, Express Down.)?
After reading this I'm sorry to say, but this is over your head an I'd say your best bet is to take your vehicle to a qualified repair shop .

Power windows inoperative

what is extra power, what is C/S???

ever seen a voltmeter. for $10 at walfart. end guessing
discover volts. put volts in you life.
the battery is 12.6vdc charged, is it ?(rested volts)
do you get 12vdc to the motor, active.?????
i bet not. ! i bet like 6v based on "extra power, statment" Hot wired is the correct word. hot wired. all motors can be tested hot wired.

and the point of voltage drop is BAD> (resistive)
its that easy.

at the low voltage of the motor, pins, backup on the wire
point by point and when it goes to 12v active , 1inch from here, is bad wire, connector or switch,.
its RESISTIVE> and bad.

this is called voltage drop testing, google that for zillion hits

I would check to see if the harness that comes to the master switch is powered. Make sure the ignition is on or vehicle running and check to see if you get voltage reading with multimeter. If no reading then you need the wiring diagram to see where that harness should be fed.

Power windows and power door locks not working

first you will need a multi meter it checks for volts, ohms which is resistance,and amps which is current,some have a beeper that goes off when you get a good curcuit now first check the switch on the door the one used the most which is the driver side door switch first remove all screws hopefully they are all phillips if not get the correct screw tip for the correct screw head and remove all the screws under and around the switch lightly tug on the switch it should move as if it wants to come out if it is still tight look for hidden screws never force anything sometimes a small flat-head screwdriver to push back plastic locking mechanisms is needed once you get the switch out it will have several wires running off of it turn the switch over with a black sharpy make a dot (where it can't be seen when the switch is installed) at one end of the switch Now draw a diagram of the wires coming out of the switch using the black dot as a reference point if you have several wires of the same color draw on the metal connector with your sharpy one line for your first black wire two lines for your second black wire etc. now that you have all of your wires removed each switch has open and closed curcuits set the multi meter on ohms touch the leads together and the display will change radialy this is a good curcuit or if you have the beeper use it by touching the leads together the meter beeps this is very handy put your red and black leads on one switch and flip the switch if it beeps the switch works check all of the switches on the multi switch panel you removed from your driver side door if any of them do not beep get a new switch from the infiniti dealer or at a on line parts store this is cheaper If they all work buy the infiniti manual at any auto parts store Next check the motor of your windows the wiring diagram in the back of the manual will have the correct voltages get a trim remover and remove the interior driver side door panel and the insulation carefully try not to rip it to much Infiniti's use the same unfortunatlly cheap made in china electronic parts as a less expensive brand cars same with the window motors, if one switch works put the motor wires on this working switch and see if the motor works if it does great, replace all the motors that are burned out and any of the switches that are also burned out also work slowly sometimes removing interior trim the plastic plugs brake pick up a few at your auto parts store and replace the broken ones .good luck

2005 Honda Accord, all three passenger power windows stopped working. The drivers window works and the window lock is not on. When I try the switch on each of the passenger windows i cvan hear a clicking...

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.

Passenger side window regulator

either it is misaligned ... the trim is gummed up ... or most likely the switches and or the harnesses to them or any of the 5 or so other connectors and 40 feet of wire between them has corroded loose or burn't terminals. A very common problem, that very few people can correct (even many mechanics) .... A voltage check would be in order at the switches (9V to 14.5V and reverses polarity depending on direction the switch is switched) and or at the motor (it could be any of those things as they all form a loop through all the wires and all switches when you operate the windows) ... it's a bit complicated for most to find or diagnose ... an automobile electric specialist would be your best bet .... unless you know your stuff and have multimeters, schematics and such.

1990 camry power window problem

It is rare that the power window relay will fail. Personally, I would look to see if there is power at the master switch on the driver's door. Anywhere. If the is NO POWER, you have a broken wire between the door & the LF kick panel where the wires come thru the body into the door shell. If there is power, the master switch is narmally the culprit

Windows won't work

Your power feed to the window switch panel is a big wire loom that goes through the driver door. Check the connection at the door jamb. I've seen the plug slowly come apart just from the door opening and closing. You should have a power window fuse at the fuse block under the dash as well. The power to all the windows goes to the main switch at the driver door first then goes to the rest of the windows. Hope this helps.
