What is the reason why the rearview mirror of Changan CS75 does not fold after locking the car?

Changan CS75's rearview mirror does not fold after locking the car because the motor is damaged, or there is a foreign object stuck in the rotation track. Foreign objects are relatively easy to deal with, just clean them up; if the motor is broken, it is more troublesome to replace it, and it is best not to do it yourself, but to find a professional to replace it. The following is relevant information about the rearview mirror: 1. The automatic folding of the exterior rearview mirror is a very convenient function, such as when passing through narrow sections or entering automatic parking spaces, the rearview mirror needs to be folded. 2. Adjust the left rearview mirror. When dealing with the up and down positions, place the distant horizon in the center, and adjust the left and right positions so that the body occupies 1/4 of the mirror surface. The key points for adjusting the left rearview mirror are to place the horizontal line in the center line of the rearview mirror, and then adjust the edge of the body to occupy 1/4 of the mirror image. 3. Adjust the right rearview mirror. Because the driver's seat is on the left, the driver's grasp of the situation on the right side of the car is not so easy, plus the need for roadside parking sometimes, the right rearview mirror should leave a larger ground area when adjusting the up and down positions, accounting for about 2/3 of the mirror surface. As for the left and right positions, adjust them so that the body occupies 1/4 of the mirror surface area.

I've been driving the Changan CS75 for three years and also encountered the issue of the side mirrors not folding when locking the car last winter. Later, I found out that the auto-folding function was turned off in the central control settings, possibly due to accidentally touching the screen. First, let me teach you how to check: go to the vehicle settings menu and find the side mirror option to see if the folding function is enabled. If the settings are correct but the mirrors still don't fold, it might be a blown fuse. Try replacing the corresponding 15A fuse in the engine compartment fuse box. In my case last time, the motor gear was stuck due to sand and mud getting in from a high-pressure water gun during car washing. Don’t force the mirrors to fold manually—the plastic gears can easily break. Replacing the motor assembly only costs about 200 yuan. I recommend going to a 4S shop to read the fault code; it takes about half an hour to locate the issue, and you can ask the technician to lubricate the pivot while you're at it. Also, freezing temperatures can cause the mirrors to stick, so spraying some anti-freeze lubricant in advance can help prevent this.

Having repaired cars for ten years, this issue with the CS75 is common. First, rule out basic scenarios: try pressing the lock button twice on the key fob to see if it triggers manually—some models require a system reset. There are five main causes: 1) A blown fuse, located in position No. 7 of the fuse box on the driver's side; 2) Worn carbon brushes in the folding motor, which can be checked by opening the housing for signs of sparking; 3) Broken door wiring harnesses, especially on the driver’s side where repeated bending can cause breaks; 4) Water ingress short-circuiting the body control module, common during rainy weather; 5) Signal interference from improperly installed dash cams that tap into wiring. Personally, I recommend checking the fuse and door wiring first—a faulty motor will produce a clicking noise. For safety, disconnect the negative battery terminal before working, and be careful not to break clips when removing door panels. If the circuit has been modified, restore factory settings before testing.

Don't worry sis, my CS75 just got this issue fixed last week. First check the settings: enter system menu via steering wheel right-side buttons, make sure 'auto mirror folding' is checked in external settings. If you hear buzzing but no movement during folding, it might be pebbles stuck in gears - just pick them out with a thin needle. The 4S shop said connector oxidation during rain could also cause failure, they fixed mine with anti-rust spray. Temporary solution: press and hold lock button for 5 seconds after engine off to force folding. Fun fact: system automatically disables this function when battery drops below 40% to protect circuits. Wear gloves if DIY - door panel edges are sharp. After repair, ask mechanic to adjust sensitivity - mine now folds instantly when locked, super convenient.
