What are the causes of abnormal noise during power mirror folding?
1 Answers
The primary cause of abnormal noise during power mirror folding is insufficient lubrication, with several other potential reasons as follows: 1. Gaps, misalignment, or displacement between leather, plastic, or wiring components. This condition is particularly prone to occur after prolonged sun exposure, causing the vehicle to produce noise due to loose parts squeezing against each other on bumpy roads. Typically, identifying the noise source and using materials like paper towels or rubber as spacers can resolve the issue. 2. Noise caused by collision between the car audio amplifier and other vehicle components. This can usually be fixed by tightening screws to secure the amplifier, CD player, etc. 3. Electrical current noise inside the vehicle. This is most noticeable during initial startup, especially when audio systems, air conditioning, or wipers activate immediately after cold starts. The noise usually disappears after the engine warms up or the vehicle has been driven for a while.
