Only One Side of My Controller Vibrates
When only one side of your controller rumbles, the cause is almost always hardware on the dead side — a snapped motor wire, a failed solder joint, or a counterweight that has slipped off the shaft. Asymmetry rules out software, because a setting or low battery silences both motors equally. The vibration test confirms which motor has failed.
Diagnose before you fix
Confirm the symptom and measure its severity first. The test result tells you whether to clean, recalibrate, or replace — different severities call for different fixes.
Vibration Test
The vibration test drives the strong (usually left) and weak (usually right) motors independently. Run each one separately and note which produces no response. Isolating the dead side in the browser — independent of any game — confirms the failure is one specific motor rather than a global setting, and tells you exactly which side to inspect when you open the controller.
Run the vibration test- A Chrome or Edge browser (best haptic support)
- A small screwdriver set
- A soldering iron (only if a motor wire has detached)
- A replacement rumble motor (only if the motor itself is dead)
Step by step
Work through these in order. After the last step, run the diagnostic again to confirm the fix held.
- 01
Isolate the dead motor with the vibration test
Open the vibration test and run the strong motor and weak motor separately, not together. Most controllers put the heavy motor (big rumbles) on the left and the light motor (subtle effects) on the right. Note which side produces nothing. If one side is fully silent, that motor or its wiring has failed. If both fire but at clearly mismatched intensity, you have a desync or a partially-failing motor rather than a fully dead one.
- 02
Rule out asymmetric game design first
Before opening anything, confirm the game actually uses both motors. Many games drive the heavy motor far more than the light one, so the right side genuinely rumbles less by design — that is not a fault. Verify in the vibration test, which drives both motors at full intensity on demand. If both respond equally in the browser but feel uneven in a game, the asymmetry is the game's haptic mix, not your controller.
- 03
Listen for a whir without shake
With the controller running the dead side in the vibration test, hold it to your ear. A faint whirring or buzzing with no physical shake means the motor spins but its counterweight has slipped off the shaft — common after a drop. Total silence means the motor isn't receiving power: a snapped wire or a failed solder joint. The sound tells you whether you're reseating a weight or repairing a connection before you even open the shell.
- 04
Open the shell and inspect the dead side
Power off, then follow an iFixit disassembly guide for your model. On the dead side, check the two motor wires where they meet the mainboard — a desoldered or snapped wire is the most common cause and is visible on inspection. Check that the motor is seated firmly in its mount; a loose motor rattles and underperforms. Reseat the counterweight if it has slipped.
CautionKeep compressed air upright and never use a metal tool near the board. Opening the controller voids the manufacturer warranty on PlayStation, Xbox, and Nintendo hardware — pursue warranty service first if the controller is covered.
- 05
Resolder or replace the motor
A detached motor wire resolders in minutes if you're comfortable with an iron. A motor that's genuinely dead (no response after confirming power reaches it) needs replacement — ERM motors are $5–15 and swap out without specialist tools. On DualSense and Switch Pro, the voice-coil/LRA actuators are more involved and pricier to replace, which often makes warranty service or controller replacement the more economical path for those models.
Where to go next
Persistent symptoms usually mean hardware wear that cleaning and recalibration can't reach. These resources cover repair, replacement, and warranty paths.
Other tests for the same controller
A symptom rarely arrives alone. Worn sticks often coincide with deadzone creep and reduced circularity — run the related diagnostics while the controller is already in your hands.

The same underlying issue presents differently across controllers. These device-specific guides cover the variations.

vibration questions
Asymmetric rumble is a hardware tell. A global cause — a vibration setting turned off, or a low-battery power-saving cutoff — silences both motors equally. When only one side is dead, the fault is specific to that motor: a snapped or desoldered wire, or a counterweight that's slipped off the motor shaft, usually after a drop. The vibration test confirms which side has failed.
Yes, by design. Controllers use a heavy motor (typically left) for big rumbles and a light motor (typically right) for subtle effects, and many games drive the heavy one far more, so the right side feels weaker in normal play. That's the game's haptic mix, not a fault. Confirm with the vibration test, which drives both motors at full intensity — if both respond there, your controller is fine.
The counterweight has slipped off the motor shaft. ERM motors create vibration by spinning an off-center weight; if that weight detaches, the motor still spins (the whir you hear) but produces no shake. It's a common after-a-drop failure and is fixable by reseating or replacing the weight, or swapping the inexpensive motor entirely.
Almost never, because the failure is physical. Firmware updates govern how both motors are driven, but they can't reconnect a snapped wire or reattach a counterweight. The rare exception is a controller-app calibration glitch — worth ruling out with a firmware update and the vibration test before opening the shell, but don't expect it to revive a genuinely dead motor.
On the overwhelming majority of controllers the heavy motor is on the left and the light motor on the right, matching the dual-rumble convention the browser haptic interface exposes as strong and weak magnitude. Run each independently in the vibration test to confirm your specific controller's layout before you open it, so you inspect the correct side.
Yes for in-warranty controllers — Sony, Microsoft, and Nintendo treat a dead motor as a hardware defect. Document the failure with the vibration test first, showing one motor responding and the other silent, which speeds the warranty claim and prevents a 'no fault found' return. Opening the shell yourself voids the warranty across all three brands, so pursue service first if you're covered.
