1. Safety First:
* Disconnect the battery: This prevents accidental shorts and shocks. Disconnect the negative (-) terminal first.
2. Access the Window Mechanism:
* Door Panel Removal: You'll need to remove the inner door panel. This usually involves removing screws around the edges, possibly under the armrest and door handle. There are often plastic clips holding it in place; carefully pry these loose with a trim removal tool to avoid breaking them. Consult a repair manual or online video specific to your Golf model for detailed instructions on door panel removal. Pictures are invaluable here.
3. Locate the Problem:
* Inspect the window regulator: Once the panel is off, you'll see the window regulator mechanism. This is the system of gears, motors, and cables that moves the window. Locate where the window has come off track. It's usually one of the following:
* Window itself: The window might have simply popped out of its guides (usually plastic rollers).
* Broken or dislodged regulator parts: A broken cable, a detached roller, or a broken regulator arm are possibilities.
* Track itself: The track itself might be damaged or dislodged.
4. Re-attach the Window:
* If the window is simply out of its guides: Carefully guide the window back into the tracks. Sometimes it helps to gently push and pull the window while guiding it back into place. It often requires aligning the window at multiple points along the track.
* If a cable is broken or detached: This is more complex. You might need to replace the entire window regulator assembly or just the cable, depending on the damage and your mechanical skills. This typically involves removing the motor and carefully manipulating the cable. This step is often more complicated than it sounds and may require specialized tools.
* If a roller is broken or dislodged: Replacing the roller will be necessary. Again, this requires a repair manual showing the parts and assembly order.
5. Test the Window:
* Reconnect the battery: After reassembling everything, carefully reconnect the battery's negative terminal.
* Test the window: Operate the power window switch several times to ensure smooth and proper operation.
6. Reassemble the Door Panel:
* Carefully reattach the door panel: Make sure all the clips and screws are correctly fastened.
Important Considerations:
* Repair Manual: A repair manual specific to your 1999 Volkswagen Golf is highly recommended. This will provide detailed diagrams and instructions, significantly easing the repair process.
* Online Videos: Search YouTube for "1999 Volkswagen Golf power window repair." Many helpful videos demonstrate the process visually.
* Parts: If parts need replacing, ensure you get genuine Volkswagen parts or high-quality aftermarket equivalents.
* Patience: This repair can be time-consuming and requires patience. Don't rush the process.
If you're not comfortable working on car mechanics, it's best to take your car to a qualified mechanic. Repairing the window regulator incorrectly could lead to further damage.
