Knowing What's Wrong with Your Ford F-150 Window Motor
You get to enjoy the fresh breeze as you drive your pick-up truck when you have a great-functioning Ford F-150 window motor. And even though it has been made to last for quite a long time, there are many factors that can negatively affect its performance. Here are some ways to know what is wrong with your car's window motor.
Poor or no electrical feed
When the motor does not work, it does not always mean that it is broken or it has gone bad. Perform a simple test on the window motor using a voltmeter. If the voltage is not enough, the motor will turn slowly. If, however, you observe that there is no voltage or ground, then electricity might not be reaching it. Check if the fuse is blown, if the relay is defective, if there are damaged wires, or if there are breaks in the electrical connections.
Broken drive rollers
The Ford F-150 window motor has a driven gear that is attached to the regulator drive gear through the use of drive rollers. The drive rollers usually give allowance for slight misalignment, and they also ensure a smooth and quiet window operation. But they can become brittle, resulting in easy breakage. When they break, the drive gear and the regulator drive gear will lose their link. The motor may run, but the window will not open or close.
The motor sticks
Sometimes, the motor simply sticks and stops working altogether. To know if this is the case, open the door panel of the affected window and give it a couple of swift taps with a small hammer. If it still doesn't work, your motor is definitely sticky. Beside this, the lubrication may also have caked out or dried up. This will prevent the gears in the motor from turning, thus disabling window operations.
The window motor relay tells the motor and the window itself where to turn. Sometimes, a set of contacts can get stuck and will make the window go down or go up by itself. Remember also that a short along the wires between the switch and the motor would also cause the problem with the motor.
