How do you replace the cabin air filter on a 1998 Mercedes-Benz C230?

This is an easy one. There are three screws under the glove box that will expose the fan and the cabin filter once the cover is removed. The cabin filter is on the left with two white plastic retaining clips approx. 2 inches long, pull the one close to you toward you and the back one away from you. This will allow the filter to drop out. Make sure the cover seats when reinstalling clips.
