What is the reason for the Mazda CX-5 rearview mirror folding malfunction?
3 Answers
Main reasons for the failure of the electric folding function of the external rearview mirror: battery disconnection or no power supply. In this case, the external mirror must be reset to function properly. The purpose of the electric folding mirror: Improve passing ability: As the widest component installed on the car, the rearview mirror is most susceptible to impact in case of friction. To minimize wear and tear, the rearview mirror needs to have a folding function. Rearview mirrors with a folding function can be retracted when passing through narrow roads, improving the car's passing ability. Avoid scratches: It can effectively reduce parking space scratches. In most cases, the rearview mirror folding button is located in the electric opening and closing area of the driver's side door, but there are exceptions, such as the gear shift base area.
I've been driving for over a decade, including a Mazda CX-5, and have encountered rearview mirror folding malfunctions several times. Common causes are mostly mechanical, such as gears getting stuck or dust and debris accumulation, especially after driving on wet or muddy roads; electrical issues like short circuits or blown fuses, for instance, when excessive current during startup causes a fuse to blow; the folding button switch becoming unresponsive or delayed; the motor itself failing, which may produce strange noises or fail to rotate; improper operation can also lead to malfunctions, such as rapidly toggling the folding function multiple times. Weather plays a significant role, with lubricants solidifying in winter making jamming more likely. To prevent issues, it's advisable to minimize use of the folding button when parking; for self-inspection, you can refer to the manual to locate the fuse and check if it's burnt out for replacement; if that doesn't work, seek professional repair to avoid damaging more components. Don't overlook this issue for safe driving—compromised parking space safety can be troublesome.
With years of experience in auto repair, I've handled numerous cases of CX-5 mirror folding malfunctions. The causes mainly fall into three categories: first, motor failure or unstable operation, possibly due to water ingress causing rust or reaching the end of its lifespan; second, broken wiring or oxidized contacts leading to signal interruption; third, malfunctioning control switches or related modules, resulting in unresponsive buttons. Additionally, blown fuses are a common trigger, located in the cabin fuse box. During inspection, use testing tools to check motor voltage; replace the fuse with the correct specification if it's blown; gently push the mirror manually to test for jamming. It's advisable not to force disassembly of parts yourself; instead, seek professional equipment at authorized service centers for quicker diagnosis. After repair, test for smooth folding to ensure each operation is effective. For prevention, regular cleaning of connection points can reduce the likelihood of issues.
