Possible Causes
When dealing with a “Toyota 4Runner back window not rolling up,” it is crucial to identify the potential root causes. There are several areas to consider, including the power window motor, power window regulator, and electrical connections.
Power Window Motor
The power window motor is responsible for controlling the movement of the window. If the motor is faulty or has failed, the back window will not roll up. This is a common issue reported by many Toyota 4Runner owners. Typically, signs of a failing motor include unusual noises, sluggish movement, or no movement at all when you attempt to operate the window.
Indicator | Symptoms |
---|---|
No Movement | Window does not respond at all |
Unusual Noises | Clicking, grinding, or whirring sounds |
Sluggish Movement | Slow or erratic window operation |

Power Window Regulator
The power window regulator is another critical component. The regulator is a mechanism that controls the up-and-down movement of the window. If the regulator is damaged or worn out, it can prevent the window from rolling up. Symptoms of a failing regulator include the window falling down inside the door, uneven movement, or the window being stuck.
Indicator | Symptoms |
---|---|
Window Falls Down | Window drops inside the door panel |
Uneven Movement | Window tilts or moves awkwardly |
Stuck Window | Window will not move at all |

Electrical Connections
Faulty or loose electrical connections can also be a culprit. If there is an issue with the wiring, switch, or harness, the power to the back window can be disrupted, causing it not to roll up. Common symptoms include intermittent operation, no response when the switch is pressed, or clicking sounds from the relay.
Indicator | Symptoms |
---|---|
Intermittent Operation | Window works sporadically |
No Response | Window does not react to the switch |
Clicking Sounds | Clicking noises when attempting to operate |
Checking the electrical connections is an essential troubleshooting step to ensure all components are functioning correctly. For more reader recommendations, refer to the discussions on 4Runners.com.

Troubleshooting Steps
When experiencing issues with your Toyota 4Runner’s rear window, it’s essential to follow a systematic approach. Here are some steps that can help diagnose why the back window is not rolling up.
Manual Operation of Regulator
One method to pinpoint the issue involves manually operating the window regulator. A failed power window regulator could be a contributing factor to the window’s malfunction. Here are the steps to do a manual operation check:
-
Locate the Regulator:
Identify where the power window regulator is situated inside your vehicle’s door panel. -
Disconnect Power:
Remove the power supply to the motor to ensure safety. -
Manually Operate:
Attempt to move the window up and down manually using the regulator mechanism. -
Assess Movement:
If the window moves freely, the issue may lie with the motor. If it doesn’t, the regulator itself might be faulty.
This attempt can provide significant insights into whether the regulator is at fault, aiding in addressing the “Toyota 4Runner back window not rolling up” problem. For further analysis and solutions, consider reading about Toyota Rav4 power back door not working.
Checking Electrical Connections
The next step is to inspect the electrical connections linked to the rear window. Faulty electrical connections could be another root cause. Below are the steps to follow:
-
Inspect Switch and Harness:
Examine the switch that controls the rear window for any visible damage or wear. Also, check the harness for secure connections. -
Test Electrical Flow:
Use a multimeter to check the electrical flow at various points. This can help identify if there’s a break in the circuit somewhere. -
Check Fuses:
Locate and examine the fuse associated with the rear window. A blown fuse could be causing the malfunction. -
Evaluate Wiring:
Inspect the wiring for any signs of damage, corrosion, or fraying. Pay extra attention to connection points and ensure they are secure. -
Reconnect and Test:
Once you have verified all connections, reconnect everything and test the window operation to see if it resolves the issue.

Systematic Diagnosis
Addressing the issue of the Toyota 4Runner back window not rolling up requires a methodical approach. Systematic diagnosis involves inspecting various electrical components to identify potential faults.
Fuse and Wiring Inspection
Inspecting the fuses and wiring is a fundamental step in diagnosing window problems. Start by checking the appropriate fuse associated with the rear window mechanism. A blown fuse can prevent the window from operating correctly.
Steps for Fuse Inspection:
- Locate the Fuse Box: Refer to the owner’s manual to find the specific location of the fuse box.
- Identify the Correct Fuse: Use the diagram provided in the fuse box cover or the manual to pinpoint the fuse responsible for the rear window.
- Inspect the Fuse: Remove the fuse and visually inspect it for any signs of damage or breakage.
- Replace if Necessary: If the fuse is blown, replace it with one of the same amperage.
If the fuse is intact, proceed to inspect the wiring:
- Examine the Wiring Harness: Check for any visible signs of wear, corrosion, or disconnection in the wiring harness connected to the rear window.
- Test Continuity: Use a multimeter to test the continuity of the wires. Ensure there are no breaks that could disrupt the electrical flow.
- Check the Switch: Inspect the switch mechanism for any faults, as a malfunctioning switch can prevent the window from operating.
