Question about 1998 Toyota 4Runner

98 4Runner rear window no longer operates

The rear window on my 98 4Runner no longer opens/closes. I have tried the center console switch, the key in the rear door lock, and verified the "child lock" is not pushed activated on the windows. Neither the key nor the switch will open the windo. I have replaced fuses and also checked the motor. The motor on the window works when jump started. What other part could be broken? Is there a relay switch to the motor?

Thank you.

    My rear window & wiper also does not work,pretty sure there is 12 volts at the blue wire all the time,also with the relay control box connected will kill battery after a few days.Just wondering what other tests could i do before replacing blue control box.
    Thanks Wade

    I have had the same problem although intermittently. I'm pretty sure its that relay box. Now I am having weird front windshield wiper problems....my wipers will go on and off sporadically and then sometimes wont turn off...no matter what setting I have them on.

    What are the other tests you mention? There is a clicking sound from the relay box whenever the rear window switch is toggled- and the same when the key is engaged into the rear hatch door. In addition, my rear wiper arm stopped functioning and I removed the arm. Would the location of the arm have some control over the function of the window (or relay)? I wonder if my relay is good, but with the wiper arm not properly located, the window does not function.

    TIA

Open the rear hatch. Pull off the inner trim panel. Look to see if there is a little box with a bunch of wires connected to it. It may be at the lower edge, driver side. Turn the key on. Test for 12 volts at the solid BLUE wire (there is only 1 solid blue wire) that is connected to the box. Is there power? If not, check the 30 amp POWER fuse. If there IS power, this box may be bad. This is the power window relay for the rear hatch. The wiper/washer and the rear window motor power all come out of this box.
BUT:
Check for power & get back to me before you buy a relay box, there are a few other tests I could share with you before we pronounce the relay box bad...

Get Door To Open With Dead Battery So I can pop the Hood Switch


I imagine the obvious answer is to use a key in the door lock cylinder. The reason you have done this is because there is no door lock cylinder! You only have a fob is my guess, that electronically opens the doors. Dead battery..and the fob no longer works. Don't worry, examine your fob and there should be a way to open it. Carefully open the fob and surprise! There is a key inside of it! Now take that key and there ahould be a key lock cylinder above your rear license plate. You should be able to open your rear hatch. Now somewhere to the drivers side in the rear compartment there should be some sort of pull you can use which will open the drivers door. Hope that helps you out!

My keyless entry for my 2008 Volvo s 40 won't work. I've tried replacing the battery but it still doesn't work. Anything I may can do before spending money on a new key.?


How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)
  • Antennas in the passenger compartment and cargo compartment
  • An antenna in the rear bumper
  • Quick lock motors in the lock units in the side doors
  • The remote keyless entry (RKE) receiver receives a signal from the key
  • The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)
  • Key-in switch.
  • Switch in door handle and lock button on handle .
    If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.

    1998 safari rear door lock / power locks


    This problem can be caused by a few things, it could be the rear door lock switch or lock module located under the dash or last the rear door actuator.

    You say that all door lock and unlock on there on, this tells me it most likely has a module problem or wiring to the rear door is bad.
    The first thing i would do would be to remove the rear door panels and check wiring to switches and actuator, then follow wiring from inside the rear hatch to where in goes through the body. the wiring most times breaks at that point where the wiring is bent over from opening and closing rear door ,

    Locate the wiring going into door or doors. sometimes the wiring only goes into one door but then sometimes in goes into both doors, check the wiring closely . it may be covered in a rubber boot . if it is covered you will need to slide boot back to check wiring.

    Good day. hope this is helpful.

    I just bought an equinox 2005 LS and I dont know how to lock the rear door.


    To unlock the liftgate, press the unlock button on the Remote Keyless Entry (RKE) transmitter twice or use the power door lock switch.
    To lock the liftgate, press the lock button on the RKE transmitter or use the power door lock switch. The liftgate does not have a key lock cylinder.
    To open the liftgate, pull up on the handle located in the center of the liftgate.
    When closing the liftgate, use the molded handles to pull the liftgate down. Push the liftgate closed until it latches.

    I have a 2000 dodge caravan sport. My rear windows will not open. I have changed the switch and they opened (the front windows work just fine and the door locks too) but the rear window will not close...


    sounds more like the wiring in drivers door faulty- worked to open after you changed it - but won't close it now- remove door panel- unplug and replug switch and try it- could be as simple as that

    Used the key to unlock door and alarm started going off. put key in ignition to start, but wouldn't. removed battery cable, do to neighbors, and the alarm keeps sounding. how can I shut it off? just...


    With the drivers window down, and the doors closed. and locked connect the battery and lock and unlock the tailgate with the key, you need to unlock it twice to unlock the doors and turn off the alarm. If the locks are working like thier supposed to the drivers door will be unlocked and opening it won't set off the alarm. the truck should be back to normal. If not disconnect the battery again. Drivers window down. Put the key in the switch and turn the key on to the run position. With all the doors closed connect the battery. connect it good and don't bounce it around. If the battery casbles aren't clean clean them good so it'll connect good. If it still is alarming then the doors switches are likly. Or the door locking motors. You should be able to lock all the doors ( including the hatch) by hand and get the system to reset. Try it all again using a different door to double unlock as a lock switch might be sticking. If the system can't verify that all the doors are closed and locked it won't reset. If you connect the battery wihg the key turned on the system thinks it's already running and appeares to be in the unset mode.

    Driver door sensor broken


    inside the mechanical lock (The part that actualy holds the door shut when you close it) there is a switch that informs the control unit that the locking mechanism is either locked or unlocked. (door open or closed).

    These switches fail sometimes, when this happens the control unit is not aware that you have closed the door
    If the faulty switch is not informing the control unit that the door is closed, the central locking will not try to lock the door (because it thinks the door is still open).
    The switch is integral with the lock unit, and they are not easy things to replace either.
    remove the internal door trim. unplugg the wiring inside. remove the outer key barrel and unhook the cable from the outer handle to the lock unit. unbolt the lock unit. the window regulator will have to be unbolted from the window (remove the 2 plastic circular access panels and wind the window down to a level at which the 2 bolts are visible), lift the window clear once unbolted (using your hands, slide it upwards in its guide rails, stick it in place with tape).
    once this is done the window regualtor can be unbolted (10 or so bolts) and removed, complete with the door lock.

    Back window doesnt roll down properly when you open the door, so I have to push it down a little before I close it. Also the lock bottom for the windows doesnt work.


    dis-connect your battery for 30 seconds to do a switch reset on your window, when you reconnect the batt your window will go down, open and close rear door to check lock functions ok first. close rear door and using key or switch inside car close window fully with out stopping, this should reset the window.

    Can't find control button to open windows on PT Cruiser


    On my 2004 PT, there are five switches in the upper center of the dashboard above the radio and heater controls. Top row is left and right front windows. bottom row is left and right rear windows, and the switch below is to disable the rear switches so the kids don't play with them. The switches in the rear are on the back of the center console between the front seats. The dashboard change (for the worse if you ask me) didn't happen until the 2006 models. The child safety locks for the back doors can be found on the front edge of the back doors when you open the front doors. If you found this helpful, please don't forget to rate it.
