1. Gather Your Supplies:
* New mirror: Obviously! Ensure it's the correct one for your 1998 Chevy Blazer S-10.
* Screwdriver(s): You'll likely need a Phillips head screwdriver, and possibly a flathead, depending on the mirror's mounting mechanism.
* Possibly a socket wrench: Some mirrors use nuts and bolts instead of screws.
* Patience: This job can be a little fiddly.
2. Remove the Old Mirror (if applicable):
* Manual Mirror: Usually involves unscrewing one or more screws holding the mirror housing to the door. These screws are often located on the back of the mirror housing, visible when the mirror is folded in. Be careful not to force anything; work gently.
* Power Mirror: This is a little more complex. You may need to disconnect the electrical connector first (usually a simple push-pull action). Then, access the mounting screws (often hidden behind a small plastic cover).
3. Install the New Mirror:
* Align the new mirror with the mounting points on the door.
* Insert the screws/bolts and tighten them securely. Don't overtighten, as you could strip the threads.
* If it's a power mirror, carefully reconnect the electrical connector. Make sure it clicks into place securely.
* Test the mirror's functionality. Adjust it to make sure it moves correctly (if it's a power mirror) and that it's securely attached.
Important Considerations:
* Type of Mirror: Make absolutely sure the replacement mirror is the correct one for your vehicle. There are variations in power/manual options and even subtle differences between years. The part number on the old mirror or a search by your VIN will help confirm.
* Glass Removal: In some cases, you might need to remove the glass from the old housing to reuse it on the new housing (especially with heated mirrors). Be gentle to avoid breaking the glass.
* Door Panel Removal: For some repairs, it may become necessary to remove the door panel to gain easier access. But often the access is fine by simply working around the edges of the door.
* Wiring: If you're replacing a power mirror with a power mirror, ensure the wiring is properly connected. A wiring diagram specific to your year and model may be helpful. If you're unsure about wiring, consult a professional.
If you're uncomfortable doing this yourself, take your Blazer to a qualified mechanic or auto body shop. They have the expertise and tools to get the job done quickly and correctly, preventing potential damage to your vehicle. It's a relatively simple job, but a mistake could lead to a more expensive repair later.
