how do you bypass electric window switch on 88 toyota pickup
To bypass the switch you will need a wiring diagram or have to use a vom meter to find the wiring layout. The local dealer can provide you with a diagram.
remove the door handle, then the interior door panel. Get the window up and down switch and then begin testing it to see if you are getting current to the switch, and from the switch to the electric motor that drives the window up and down. If you can bypass the switch and jump 12 volts past the switch, and the morot works and the window moves, then it's the switch. If you bypass the switch and the motor does not operate the window, then the motor is probably bad. More than likey it is the switch........but these are ways to tell. You will need a multimeter to check voltage levels and a jumper wire to bypass the switch. You should buy a door panel removal tool too. It will save you money before you bust the door panel trying to pull it off. It slips behind the door panel and pops the plastic screws that hold the door panel in place. And mkae sure you look all around the door panel for hidden screws. Designers spend hours trying to hide them from sight.
MY DRIVERS WINDOW WAS STUCK IN THE DOWN POSITION, I CHANGED THE WINDOW SWITCH BUT IT DID NOT HELP, I FOUND OUT THAT WHEN I USE THE EXPRESS DOWN THE WINDOW STICKS IN THE DOWN POSITION. I BANGED ON THE DOOR PANEL AND IT STARTED WORKING. NOW I DO NOT USE THE EXPRESS AND I DON'T RUN THE WINDOW ALL THE WAY DOWN TILL I CAN SWAP IT OUT
Remove the decorative cover to the window switch panel. Remove the window switch retaining screws. Remove the wiring harness from the back of the window switch. Reverse the process to install the new window switch.
As far as I know there is no way to get the window down other than removing the motor itself. The motor is what holds the window up when closed. Make sure its the motor that has failed. There is also a switch located on the drivers side latch inside the gate that is designed to not allow the window to open when the gate is down. If that switch fails it the window motor will not function at all. I used a wire jumper to bypass the switch and solved my problem.
The drivers window switch on the master switch energizes a solenoid for the express down feature of the drivers window. The solenoid deenergizes when the window bottoms out causing the thermal overload in the window motor to open. A spring in the solenoid is supposed to break the open circuit and provide power to the close circuit when deenergized. Sometimes the spring gets weak or the solenoid plunger is sticky preventing powering the close circuit. Removing the door panel and diaassembling the master switch is not a DIY. I have had success banging on the arm rest adjacent to the master switch to get the spring to make the close circuit. My guess is the rear window switch gets its power from the same movable contact as the drivers window switch.
take of the door panel and apply power and ground to the motor only takes about 10 minutes to get the panel on and off.
Smash the window
Check the switch first to see if it's getting juice (bypass) If it is, see if motor is binding. You will have to pull panel on said door.
The drivers side switch is the master switch; all power goes thru this switch. Pop it out and test for power; you may just have a bad connection at the switch. I would also check the window lock switch and bypass it to make sure that is not the problem.
Not really! Have you tried unhooking the negative battery cable? If it then works for a few minutes, it is a sensor inside the door! I am working on a bypass for this common problem! A toggle switch for the window RELAY.
