Symptoms
- Window rises when you hold the switch but drops once released
- Window may fall suddenly and fully into the door
- No unusual sound necessarily, just loss of holding position
- Motor may still sound like it's working
Likely causes
- CommonBroken regulator cableCable-style regulators rely on tension; a snapped cable can't hold the glass up.
- CommonStripped or broken regulator clamp/clipThe clamp holding the glass to the regulator arm can wear out or crack.
- PossibleWorn regulator gear (in gear-driven types)Stripped gear teeth can let the mechanism slip under the weight of the glass.
- Less commonMotor unable to hold position due to internal wearSome motors lose their ability to hold position as brushes wear internally.
What to do
- Avoid rolling the window down further if it's currently up, since it may not come back up once lowered.
- Use tape across the top of the glass and frame temporarily if you must leave the car and it won't hold up.
- Have the door panel removed to inspect the regulator cable, clamp, or gear for damage.
- Replace the specific broken or worn component, which is often bundled with the regulator assembly.
- Test the window through several full up-and-down cycles after repair to confirm it holds position.
- Get this fixed promptly, since a window that won't stay up leaves the car exposed to weather and theft.
Tools and parts
- Trim removal tool
- Tape (temporary measure)

When to call a pro
See a shop soon if the window won't hold up, since driving with it down or improvised shut isn't a lasting solution.
