In most cases, the passenger window not rising is an electrical issue rather than a glass or frame problem. A blown fuse, a failing window motor or regulator, or a faulty window switch are the most common culprits.
Beyond those basics, wiring problems inside the door, a blocked window track, or an active window lock can also prevent the window from moving upward. The Avenger uses both a passenger switch and a driver’s master switch, so issues can appear on one or both controls. A structured check can help you identify the exact cause before replacing parts.
Common causes
These are the typical culprits that prevent the passenger window from moving upward on a 2012 Dodge Avenger.
- Blown fuse or faulty relay in the power window circuit
- Faulty passenger window switch or driver’s master switch
- Failing window motor or a stuck/regulating window mechanism
- Damaged wiring or a bad door connector inside the door
- Window track obstruction or binding that prevents movement
- Window lock or child safety feature engaged on the driver’s control
The above covers the most common failure modes. If none of these conditions are met, more in-depth electrical or mechanical testing may be required by a professional.
Step-by-step diagnostic guide
Follow these steps to isolate the problem safely. Start with the least invasive checks before moving to components inside the door.
- Check the power window fuses and relays. Locate the interior fuse box, identify the Power Window fuse/relay, and replace if blown. If the fuse repeatedly blows, there is an underlying fault.
- Test both window switches. Use the passenger switch and the driver’s master switch. If one works and the other doesn’t, the faulty switch is likely the cause; if neither works, the issue may be the motor, regulator, or wiring.
- Listen for the window motor when pressing Up. A buzzing or humming sound with no movement suggests a motor or regulator problem; a distinct click could indicate a relay or motor fault.
- Inspect the door wiring harness and connectors. Remove the door panel carefully and check for damaged, loose, or corroded wires; reseat connectors and look for signs of wear from opening/closing the door.
- Assess for regulator or track binding. If the window moves slowly or stalls, the regulator or track may be worn or obstructed; avoid forcing the glass, as that can damage the glass and regulator.
- Check window lock settings. Ensure the window lock is not engaged on the driver’s control; disabling it should restore control to both switches on most models.
Conclusion: If you cannot identify the fault with these checks, or if the wiring and switch tests pass but the window still won’t rise, professional service is advisable. Replacing a window motor or regulator and repairing door wiring typically requires removing the door panel and using specialized tools.
What to expect if you visit a professional
A mechanic will usually diagnose with voltage tests, continuity checks, and testing of the switch, motor, and regulator. Repairs may include replacing the window motor, the regulator, the wiring harness, or the switches, depending on the exact fault.
Summary
The most common causes for a passenger window that won’t go up on a 2012 Dodge Avenger are a blown fuse, a faulty window motor or regulator, or a bad window switch. Start with checking fuses and switches, then test the motor and door wiring, and look for track binding. If the issue persists, professional diagnosis is recommended to avoid further damage and to ensure the correct component is replaced.
