Where Is The Mercedes CLK63 Starter Relay Located?
Finding the Mercedes CLK63 starter relay always seems to come up when your car refuses to start. On most CLK63s, you’ll want to look inside the fuse box under the hood. Usually, you'll find it on the driver’s side, nestled close to other relays and fuses. Lift the fuse box cover and check underneath; Mercedes often puts a diagram there to show which relay does what. If you’re working under the hood, disconnect the battery first. You want to stay safe and cut the risk of unplanned sparks. Most techs head straight to this spot when the starter isn’t doing its job.
What Are The Symptoms Of A Bad Mercedes CLK63 Starter Relay?
A worn out or sticking Mercedes CLK63 starter relay tends to leave you stranded without warning. You turn the key and nothing happens—no crank, no engine noise, sometimes just one sharp click. Other times, the engine might start after you try it a couple of times, but it’s hit or miss. Occasionally, you’ll hear the starter dragging on or not catching at all. Some drivers notice a dash warning, but not always. Once in a while, it’ll cause the engine to keep cranking even when you stop, but that’s rare. If a jump start fixes it, it points toward the relay or its wiring, rather than a dead battery.
How Do You Test The Mercedes CLK63 Starter Relay?
To check the Mercedes CLK63 starter relay, open the fuse box and find the relay—use the map if you need to. Listen as someone turns the key: a healthy relay usually makes a soft click. If it’s quiet, odds are it’s bad. Grab a multimeter, set it to voltage, and check both the power and control pins while twisting the key. Everything matching the specs? The relay might be fine. If not, swap in a relay from another slot—just make sure it's the same type. If the car starts now, the old relay was at fault. Double-check all wires and connectors before wrapping up.
Can A Mercedes CLK63 Starter Relay Be Repaired, Or Does It Need Replacement?
The question comes up: Is it worth opening up a Mercedes CLK63 starter relay, or do you just buy a new one? Most of the time, relays aren’t built to be taken apart. The contacts wear down or get stuck, and replacement ends up being much faster and more reliable. Pop out the old relay, push in a new one, and you’re usually in the clear. Relays cost much less than a lot of other electrical parts. If the same relay keeps dying, check for wiring issues or something else pulling too much current, since a bad part somewhere else could be the real problem.
Could Other Issues Mimic A Faulty Mercedes CLK63 Starter Relay?
Not every no-start means your Mercedes CLK63 starter relay is toast. Batteries give up, cables corrode, ignition switches break, starters burn out—a lot can go wrong. Sometimes, even the immobilizer can block the signal. Mechanics take a step back and test each piece in turn to see what actually failed. Always start by making sure the battery is fully charged and all the major wires are secure and free of corrosion. Only swap the relay after double-checking these other usual suspects.
