Possible reasons why your rear windows won't go down:
* Power window motor: The motor that controls the windows might be faulty. It could be burned out or have a broken gear.
* Window regulator: The mechanism that raises and lowers the windows could be broken. This could include a broken cable, a bent arm, or a worn-out gear.
* Wiring: There could be a problem with the wiring to the window motor, regulator, or switch. This could include a broken wire, a loose connection, or a short circuit.
* Switch: The window switch itself could be faulty. This could be a simple problem like a stuck button, or a more serious issue with the switch itself.
* Fuse: A blown fuse could be preventing power from reaching the window motor. Check the fuse box for a blown fuse related to the windows.
* Stuck window: Sometimes, the window itself can get stuck due to debris, a damaged seal, or a buildup of condensation.
How to troubleshoot:
1. Check the fuses: Make sure the fuse for the windows is not blown.
2. Inspect the wiring: Look for any visible damage to the wiring.
3. Test the window switch: Try pushing the switch in different directions to see if it is working.
4. Listen for motor noise: When you press the window switch, you should hear the window motor running. If you don't, the motor might be faulty.
5. Manually try the window: If you can access the window mechanism, try to manually raise or lower the window to see if it is stuck.
Important Note: If you are not comfortable working on your car, it's best to take it to a mechanic to get it diagnosed and repaired.
