Buy Mercedes-Benz CLK320 Mirror Glass

The mirror glass on a Mercedes-Benz CLK320-also called side-view glass, wing-mirror lens, or door-mirror glass-lets you see traffic beside and behind the car. Replacing cracked or hazy glass quickly keeps you legal and safe. The CLK320 (model years 1998-2003) is part of the first-generation W208 CLK-Class, so most replacement panes are sized and clipped for that housing . Modern mirror glass can be flat, convex, heated, or electro-chromic (auto-dimming), and each style affects what you see and how you install it.

• Fits 1998-2003 CLK320 coupé and cabriolet housings; does not fit the later W209 body.
• Driver-side glass must be flat (unit-magnification) to meet U.S. FMVSS 111 rules , (nhtsa.gov).
• Passenger-side glass may be convex to widen the field of view, which is why it carries the "Objects in mirror are closer than they appear" marking .

• Auto-dimming: Light sensors trigger an electro-chromic layer to darken in milliseconds, reducing headlight glare and eye strain .
• Blind-spot monitoring: Newer mirrors may hide LEDs linked to radar modules that warn when a vehicle sits in the blind zone .
• Camera mirrors: Carmakers are lobbying to replace bulky housings with cameras to cut drag and wind noise . Until laws change, glass remains mandatory.

• United States: FMVSS 111 demands a flat driver mirror and sets minimum rearward field-of-view angles .
• Europe: Heavy trucks must use wide-angle blind-spot mirrors since 2007; passenger-car standards mirror (pun intended) UN Regulation 46 .
• Mirror condition: Most states fine drivers for broken glass that hinders 200 ft (≈60 m) rear visibility .

• Brown stains or bubbling: Electro-chromic fluid leak-replace glass; cleaning won't fix it .
• Defrost never clears: Check fuse F5 in the under-hood box; if intact, test the two heating pins on the back of the glass with a multimeter.
• Double image or distortion: Wrong curvature; verify part matches left vs. right.

1. Protect paint. Tape around the housing.
2. Tilt mirror inward. Gives finger room.
3. Pop the glass. Use gloved fingers or a trim tool at the inner edge-clips release with firm pressure.
4. Disconnect heaters. Two spade connectors; note orientation.
5. Apply new pane. If your replacement is stick-on, clean old surface with isopropyl, then use a high-bond acrylic adhesive rated -30 °F to 230 °F .
6. Test functions before driving.

Tip: Warm the housing with a hair dryer in cold weather so clips flex instead of cracking.

• Keep glass clean with non-ammonia spray; ammonia can haze electro-chromic coatings.
• Activate rear defroster for five minutes to dry condensation on heated mirrors.
• Fold mirrors when parked to avoid curb strikes; impacts loosen internal clips over time.

Proper aim erases most blind spots. Lean until your forehead touches the driver-window glass, set the left mirror so only a sliver of your car shows, then lean over the center console and repeat on the right . A quick shoulder check still matters, but this setup dramatically widens what you see.
