What are the reasons for the automatic opening of the Accord window?

The reasons for the automatic opening of the Accord window are: 1. The car door circuit is damp or water enters, causing line confusion, which leads to the car window controller receiving wrong signals; 2. The circuit of the control button on the car driver's seat is short-circuited; 3. The glass automatic lifter is damaged. The Accord is a mid-size SUV launched by GAC Honda, with a length, width and height of 4858mm, 1942mm and 1670mm respectively, and a wheelbase of 2820mm. It is equipped with 1.5T and 2.0T turbocharged engines, with maximum power of 142kw and 200kw respectively, matched with CVT continuously variable transmission and 9-speed automatic manual transmission.
I've been studying cars for over a decade. The automatic window opening issue with the Avancier is quite common, likely caused by short circuits due to aging electrical systems, especially when wiring near the window switches wears out and triggers false activations. If the remote key buttons get stuck or the battery runs low, they can also send incorrect signals; another possibility is sporadic faults in the body control module—my old car once had windows opening by themselves due to module overheating, but thankfully I got it repaired in time. Fuse blowouts or poor relay contact could also be culprits, which require testing with a multimeter. My advice: first check the key and switch conditions, don’t make the same mistake I did by letting small issues escalate. Safety comes first—regular maintenance can prevent 90% of these troubles.
Last year, my new Crown also experienced the issue of windows opening unexpectedly, which was quite annoying. It was probably due to a malfunction in the key remote control function, where the buttons weren't working properly and caused unintended actions. Alternatively, the switch itself might have had issues, such as rainwater seeping in and corroding the contacts. Sometimes, the electronic system can act up, and bugs may occur if the software updates aren't properly installed. I later went to the dealership to refresh the firmware, and that solved the problem. Humid or hot weather might also affect signal transmission. I tried reinstalling the battery's positive terminal, which worked temporarily but didn't address the root cause. If anyone encounters this issue, don't panic—try testing with a spare key first, as it can save time and effort.
