How to Unlock an Electric Window: 3 Simple Steps
You don't need to drive your car to the garage to unlock an electric window. In just one afternoon you will be able to solve this problem on your own. Here are the three steps to follow.
When one of your electric windows is blocked, the first thing to check is the fuse.
- If the fuse is OK, the problem is either a bad switch or motor, or a broken regulator (the device that raises and lowers the window).
- To complete the repair, you will need a voltmeter, a metric socket set, a screwdriver, a drill and most importantly, an online subscription to a service manual.
This type of subscription will allow you to download instructions and diagrams specific to your car.
The instructions in this article are helpful as a guide, but you will need to consult your vehicle manufacturer's manual for more details.
1. Remove the Trim Panel
- First, remove all fasteners from the trim panel to gain access to the switch for testing.
- Remove the trim panel and peel off the vapor barrier.
- You can pick up a specific removal tool for just $ 5 (at an auto parts store) and you'll save precious time.
2. Tests to be Carried out with Your Voltmeter
- Unplug the window motor power connector located in the door panel (be sure to wear leather gloves to protect against cuts).
- Connect the wires from your voltmeter to the two connector terminals.
- Turn the key to the "on" position and push the glass toggle switch up and down.
- If the switch works, the read voltage will drop from +12 volts to -12 volts.
- This means that the problem is with the engine / governor.
- If the voltmeter does not display these voltages, it means the switch is damaged or a broken power or ground wire.
- Download an electrical diagram and check the electrical and ground wires leading to the switch to isolate the problem.
3. Replace the Old Regulator
If you need to remove the window regulator, you must first remove the glass.
- Tilt the glass away from the door and lift up to remove it.
- Then remove the regulator bolts or rivets.
- With the drill, extract the bolts and remove the old regulator through one of the openings in the door panel.
- Reverse this procedure to install the new regulator.
- Screw the new regulator into place, then reinstall the motor and window switch electrical connectors and glass.
- Test the window to see if it is working properly.
- If the glass creaks, loosen the bolts and make some minor adjustments to the regulator.
- Then, tighten the assembly and replace the vapor barrier and trim panel.
These little tips will be invaluable to you the next time you have to unlock an electric window, and the repair will be a breeze.
