1. Preparation:
* Disconnect the battery's negative terminal. This is crucial to prevent accidental short circuits.
2. Accessing the Mirror:
* Locate the release mechanism: Most likely, there will be a small, possibly recessed, button or clip on the top or bottom of the mirror's base. You might need a small flat-head screwdriver or trim tool to gently pry or push this release. Examine the mirror closely; the mechanism might not be immediately obvious. Some models have a small hole where you can insert a thin tool to release the mirror.
3. Removing the Mirror:
* Once the release is activated: Gently pull the mirror away from the windshield. It should come free. There might be a slight resistance; don't force it, as you could break something.
Important Considerations:
* Auto-dimming mirror: If your rearview mirror is auto-dimming, it might have a more complex removal process involving additional connectors. Carefully inspect the back of the mirror for wiring harnesses or other connections before pulling on it. You'll need to disconnect these before removing the mirror.
* Integrated features: Some rearview mirrors have integrated features like compass or temperature displays. These might have separate wiring harnesses that need to be disconnected before removal.
* Damage: Be extremely gentle. The plastic housing surrounding the mirror and its mount are relatively fragile. A cracked windshield is an even more costly repair than a broken mirror.
If you're unsure about any of these steps:
* Consult a repair manual: A repair manual specific to your 1998 Pontiac GTP will provide detailed instructions with diagrams.
* Seek professional help: If you're uncomfortable working on your car, it's best to take it to a qualified mechanic. They have the experience and tools to remove the mirror safely and efficiently.
Remember safety first! Always disconnect the battery negative terminal before attempting any electrical work on your vehicle.
