How Do I Replace The Mercedes S320 Mirror Switch?
To swap out the Mercedes S320 mirror switch, start by using a trim tool to work around the edges and lift the switch panel. Some panels pop out, but yours may have two screws—these are usually tucked under the trim. Once you see them, take out the screws. Now you can pull the switch forward. Try not to tug on the wires. Instead, find the connector at the back of the switch and squeeze the tab to unplug it. With the old switch out, just plug in the new one, fasten the screws again, and press the trim or panel into place. It's a good move to disconnect your battery first so there's no risk of a short. When you're done, test the switch to make sure both mirrors respond.
Why Is My Mercedes S320 Mirror Switch Not Working?
If your Mercedes S320 mirror switch isn’t doing anything, first check the fuse box—more than one owner has found the culprit there. See if other controls on your door work, like the window switches. If those are dead as well, you probably have a wiring issue or a failed fuse. Sometimes spilled coffee or just years of dust build up inside the switch. Pull the switch out and look at the connectors for corrosion or anything sticky. If it looks clean and the fuse is fine, you might be dealing with a bad switch—try borrowing a working mirror switch and popping it in to see if that brings back function.
Can The Mercedes S320 Mirror Switch Be Repaired Or Must It Be Replaced?
Many people wonder whether it’s worth opening up the Mercedes S320 mirror switch and attempting a fix. Gummed up buttons or slow responses sometimes improve with a good clean. Carefully pop the switch open, wipe the contact points and see if that helps. Bent springs or worn metal inside might be replaceable if you’re patient—just be sure to reassemble everything tightly. If you spot cracked plastic, heavy corrosion, or a burnt board inside, replacement is the safer bet. Sometimes you can pick up a used one from a salvage yard if new is out of budget.
Are Aftermarket Mirror Switches Reliable For The S320?
Choosing an aftermarket Mercedes S320 mirror switch comes down to risk and reward. Some drivers get lucky with perfectly fitting aftermarket switches that last for years. Others run into clunky buttons or switches that fail after a few months. The difference often comes down to which company made the part. Always check reviews and look for brands that back their products with a warranty. Before you order, compare photos and make sure the plug and mounting points match up with your old switch. If you want hassle-free repairs, sometimes it’s worth spending a bit more or going with a recycled original part from a trusted source.
How Do I Diagnose Wiring Issues Related To The S320 Mirror Switch?
Fixing wiring issues for your Mercedes S320 mirror switch starts with a careful look at the door’s harness, especially in the spot where wires flex near the hinges. Pull back any boot or cover and check for broken or split wires. Get a wiring diagram for your car’s model year so you know which color wire does what. Using a meter, check continuity from the switch plug to both the fuse and the mirror motor. If you don’t get voltage at the mirror when you press the switch, work backwards until you find where the power drops off. Damage near the hinge or moisture inside the door causes most of these wiring headaches.
