Car sun visors generally come in two types: manual and automatic. Manual visors are operated by hand, while automatic visors contain a motor and sensor that dictate the position of the shade. Manual visors typically cover only a portion of the windshield while automatic visors can cover the windshield entirely.
A vehicle sun visor can contain a mirror, light and extensions. When replacing a sun visor, confirm that the replacement part has the glass intact, a functioning light and extensions that slide in and out easily. Also ensure that all the necessary screws, clips and mounting aids are included, and that the entire assembly is free from any tears, nicks, stains and other forms of damage.
