When the power windows of your Honda Accord malfunction, it may not be a big deal. But when your power windows malfunction during a sand storm or in rainy whether, it may be the biggest deal of your life. That said, this article will help you isolate the possible sources causing your car's power windows to fail, and how they can be resolved. There are telltale signs of what may be causing the malfunction, and other causes might be more discreet. Here are a few tips, costs, and basic actions that might prevent or fix your car's power window malfunction.

Pro Tip

Before any window repair, make sure the run channels are clean. At times, dirt and debris can get trapped or hamper the power window's functionality.

Step 1 – What's the condition of the master switch?

The master switch (located in the driver's side) controls the power window functionality. This switch is prone to malfunction if the power wires connected to it are damaged, and no longer transmitting power. Among the Accord community, owners admit that damage to the master switch is largely attributed to spilled beverages, or if the windows are left open when it rains. This exposure to water or other liquids results in electrical resistance that causes the switch to overheat and melt the wires. Additionally, a melting switch can produce smoke and cause a fire.

If you suspect that the master switch is damaged or faulty, best to replace it. A master switch costs between $25 to $85. It's an easy DIY task, but if you'd rather not touch it, labor costs for repair start at $100.

Step 2 – How is the window regulator?

The window regulator anchors the mirrors, and propels them up or down when the power window switches are pressed; it relies on a motor to turn its gears. As such, it's a friction intensive component, and over time its hinges or the gears wear out. When the power window regulator fails, the windows of your Accord can plunge deep into the door frame and get trapped there. If this is the cause, you should hear the window rattling around behind the door panel.

Motoring experts suggest replacing the power window regulator, as tightening its minor components may not completely resolve the issue. The regulator by itself costs around $50. At a dealership or auto shop, parts and labor costs upwards of $350. So replacing it yourself might be the best option.

Step 3 – Is the regulator motor running?

A worn out or dried weather strip will slow down the window's movement, over-exerting the motor driving the power window regulator and hastening its damage. If you notice that a windows move slowly and the weather strip is dried up, spraying it with silicone lubricant might salvage its ability to assist with the window's movement.

Another problem could unknowingly be that the motor fails from inefficient power or no power at all. Connect a voltmeter to the power window wires, and test if the power is actually being transmitted. But if the power and wires are running or intact, the regulator motor should be replaced. They cost anywhere from $30 to $110.
