Why does my car window make a grinding or clicking noise?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
A grinding or clicking noise when a window moves usually comes from the regulator: a stripped gear, a broken clip, or a binding arm. The motor may also be failing. Stop using the window to avoid more damage, since a failing regulator can drop the glass into the door. The repair is available at the shop or mobile.
Grinding or clicking noise → likely cause
The noise a window makes points to the part inside the door that is failing.
| Noise | Likely cause |
|---|---|
| Grinding when rolling the window down | A stripped regulator gear or a binding arm |
| Clicking inside the door | A broken clip that no longer holds the glass to the regulator |
| Noise only going up | A tired motor straining under load |
| Noise and the window drops | The regulator or its clips have failed, dropping the glass |
| Noise and the window is crooked | The glass has slipped off track from a failed clip |
Why is my car window making noise going up?
The regulator is the mechanism inside the door that lifts and lowers the glass, and most window noises trace back to it. A grinding sound often means a gear on the regulator is stripped or an arm is binding against the track. A clicking sound usually points to a clip that has broken, so the glass is no longer held firmly and rattles or catches as it moves.
The motor can also be the source. A tired motor strains under load, and the noise it makes is loudest near the top of the travel, where the glass meets the most resistance. If the window is slow as well as noisy, the motor is a likely suspect.
The safest move is to stop using the window. A failing regulator can let go completely and drop the glass into the door, where it may shatter. The work is done at the shop or mobile, where the technician inspects the regulator, clips, and motor, then replaces the failed part. See our guide on what a window regulator is.
Stop using a noisy window
A grinding or clicking regulator can fail completely and drop the glass into the door, where it may shatter. Stop using the window and have the regulator and motor checked. If the glass has already dropped, it is replaced and the cavity is vacuumed as part of the job.
More questions about noisy windows
Why is there a grinding noise when rolling my window down?
A stripped regulator gear or a binding arm is the usual cause. The regulator is the lift mechanism inside the door, and a failing gear grinds as it turns. Stop using the window and have it inspected.
What is the clicking noise in my car door?
A broken clip that no longer holds the glass to the regulator is the likely cause. The glass rattles or catches as it moves, producing a click. The clip is replaced as part of the regulator repair.
Should I keep using a window that makes noise?
No. A failing regulator can let go and drop the glass into the door, where it may shatter. Stop using the window and book regulator and motor repair, available at the shop or mobile.
