Important things to consider:

• The kind of the component: A flat one reflects the situation on the road without distortion, but it only gives the driver a limited field of vision. Convex and aspherical products visually distort objects, but they provide a larger field of view.
• Adjustment mechanism: A cable system is simple and reliable. The component can be adjusted with the help of a special lever fitted in the cabin near the mirror mounting location. Power mirrors are adjusted using control switches. This type of adjustment is more accurate and convenient.
• Anti-glare coating: These products can be, for example, of tinted type. They reduce the risk of being dazzled at night. On the other hand, if the tint is too dark, it can have a negative impact on the reflective properties of the part.
• Additional features: heating, a blind spot sensor, a turn indicator repeater, a built-in camera.

Disassembling the component involves removing the mirror glass from its housing. In order to do this:

1. Pull the mirror glass to the side until it will go no further.
2. Remove it from the retaining clips. Use a plastic pry tool if you cannot do this by hand.
3. Disconnect the wires from the mirror glass. You can then carefully remove it from the housing.

The procedure for removing the part depends on the make and model of the car, but usually consists of the following steps:

1. Turn off the engine and let it cool down.
2. Disconnect the negative battery terminal.
3. Open the door and remove the plastic cover from the mirror fasteners. For manually adjustable components, remove the retainer from the mirror position regulator.
4. Disconnect the electric wires, or cables if the component is manually adjustable.
5. Hold or secure the part to prevent its falling.
6. Remove the fasteners from the inside of the door and, if necessary, the regulator.
7. Disconnect the component.
