Rear Window Sunshade Fails and Makes Grinding Noise on Lexus LS400

The motor for the rear window sunshade in the Lexus LS400 is known to fail. When this occurs, the sunshade will not extend over the window, and a grinding noise is heard until the motor fails as well.

Replacement of the sunshade assembly is necessary to correct this failure, however, removing the fuse for the sunshade will stop the motor from making the irritating grinding noise.
