Why does the left front door window switch of the Haval H5 fail?
3 Answers
Haval H5 left front door window switch failure may be caused by deformation or damage to the window's mud channel; loose screws fixing the window regulator; or damage to the window regulator itself. Deformation or damage to the window's mud channel: Deformation or damage to the window's mud channel can result in the left front door window switch failure. Loose screws fixing the window regulator: Loose or insecure screws fixing the window regulator can cause the window switch to fail. The solution is to turn on the ignition switch, hold the switch in the up position, and after the window reaches the top, continue holding for more than 3 seconds. Then release the switch and immediately press and hold it down to lower the window to the bottom for more than 3 seconds. Repeat the upward movement once more to complete the initialization procedure, restoring the window's lifting function. This method is effective for most vehicle models. If the function is not restored, it is necessary to visit a professional repair shop for inspection.
I once encountered an issue with the malfunctioning power window switch on the left front door of my Haval H5. It happened when I was on the highway and found the switch unresponsive, likely due to worn internal contacts or accumulated dirt inside the switch button. I also checked the fuse box to see if the corresponding fuse had blown (usually located in the box under the driver's seat). Sometimes, it's caused by a loose wiring harness, especially the door wiring harness, which is prone to issues after rain or rough driving. If other switches work fine, it generally rules out motor failure, but it's best not to attempt disassembly yourself. After measuring unstable voltage with a multimeter, I went straight to the 4S dealership. During maintenance, try to minimize using the switch to prevent water accumulation in the door. This problem is actually quite common, and delaying repairs can affect door operation convenience and even compromise safety, which shouldn't be overlooked.
When I was driving my Haval H5, the left front door window switch suddenly stopped working. At first, I thought I might have pressed the button too hard and damaged it. In most cases, it's either the switch button getting stuck or a loose wiring connection, as the metal contacts tend to oxidize with age. It could also be a blown fuse—those tiny things can have a big impact. I checked the fuse box myself and tried simply replacing it (the Haval manual has a location diagram). If that doesn’t work, I’ll call a mechanic. Additionally, if the door control module gets damp or fails, it can affect the entire system, so I recommend not spraying too hard when washing the car. This issue isn’t major, but it needs timely attention—otherwise, the window might get stuck, which could be troublesome in an emergency if you can’t open it.
