Why can the Honda Fit window regulator only go down but not up?

Honda Fit window regulator can only go down but not up may be due to a car window switch issue. Here is an introduction to car window lift knowledge: Introduction: Whether it is controlled by a smart key or a mechanical button, one-touch window operation generally has an "anti-pinch" function. During the automatic closing operation, if an object is caught between the glass and the window frame, the window closing operation will automatically stop midway and return to the initial state; otherwise, it may pose a risk of pinching. Working principle: Each power window has an Electric Window Control Module (ECM). When you press the power window control switch, the ECM starts receiving signals from the control switch. If the switch is pressed for less than 0.5 seconds, the ECM will control the window to fully open or close. If the switch is pressed for more than 0.5 seconds, the ECM will continuously power the window motor, and the window will only stop rising or falling when the switch is released.
When my Honda Fit encountered this issue, I looked it up and found that it might be due to worn or oxidized internal contacts in the window switch button, causing only the down signal to pass while the up signal fails. Another common reason is a malfunction in one side of the window motor or poor wire contact, such as a loose or corroded connector. It could also be due to foreign objects stuck in the guide rails or insufficient lubrication, causing the window to move only in one direction. I suggest trying simple DIY fixes first: gently tap the switch panel a few times to see if it temporarily restores function, or check if the related fuses in the fuse box are blown. If these don’t work, visit a repair shop promptly for diagnosis and part replacement. Otherwise, leaving the window open during rain can lead to water damage to the interior or electronic systems, significantly compromising safety. Regular cleaning of window gaps and applying lubricant can help prevent such issues.
