1. Understanding the Clamp:
The clamp is designed to grip the windshield tightly. It likely has two parts:
* The base: This is the part that attaches to the windshield.
* The arms: These are spring-loaded arms that squeeze against the windshield to hold the mirror. They might be partially hidden within the base.
2. Preparation:
* Clean the Windshield: Make sure the area where the mirror mounts is perfectly clean and dry. Any dirt or debris will prevent a secure fit and can lead to the mirror falling off. Use glass cleaner and a lint-free cloth.
* Examine the Clamp: Carefully inspect the clamp itself. Are there any broken parts? Are the arms still springy? If anything's broken, you'll need a replacement mirror or clamp.
3. Reinstallation Process:
This is the most challenging part, and it's often easier with two people:
* Positioning the Base: Carefully position the base of the clamp on the windshield where the mirror should sit. Make sure it's aligned correctly.
* Gently Squeeze the Arms: With one hand, gently but firmly push the arms of the clamp toward the windshield. This is where having a second person can be helpful – one person can hold the base steady while the other squeezes the arms.
* Secure the Mirror: Once the arms are firmly against the windshield, carefully attach the mirror to the base. There's usually a simple locking mechanism to secure the mirror to the clamp.
* Test the Fit: Gently try to pull the mirror to ensure it’s securely fastened to the windshield. If it moves easily, the clamp isn't gripping properly, and you’ll need to repeat steps 3a and 3b.
Troubleshooting:
* If the clamp doesn't seem to have enough spring tension: There might be an issue with the clamp itself. You might need a replacement.
* If the arms are bending or breaking: Don't force it. Stop and get a new clamp or mirror.
* If it still doesn't work: Consider consulting a professional auto glass installer. They've worked with these types of mirrors before and can likely resolve the issue quickly.
Important Notes:
* Be Gentle: Avoid using excessive force, which can damage the windshield or the mirror assembly.
* Replacement Parts: If the clamp is broken, finding a replacement might require visiting a junkyard, searching online parts stores (using the year, make, and model of your Grand Prix), or going to a dealership. Specifying "auto-dimming" is crucial for getting the correct part.
If you can provide a picture of the clamp, it would make it easier to give more specific guidance.
