2001-2002 Chevrolet Prizm Rear View Mirror: Decoding LSi, Map Lights, and the Sunroof Exception

Symptoms of a Failing Rear View Mirror

Failure of the interior rear view mirror on a 2001-2002 Prizm is typically straightforward to diagnose. Symptoms will vary depending on the type of failure.

• Mirror is Loose or Drifting: The most common issue is a loose ball joint where the mirror pivots. The mirror will not hold its position, often drooping downwards and requiring constant readjustment. This is caused by wear and tear from adjusting the mirror over many years.
• Mirror Falls Off Windshield: The mirror assembly may detach from the windshield entirely. This is not a failure of the mirror itself, but of the adhesive that bonds the metal mounting button to the glass. High heat and humidity can weaken the glue over time, causing it to fail.
• Cracked or Distorted Glass: Physical impact can crack the mirror glass. Less commonly, the reflective coating on the back of the glass can degrade, causing dark spots or a distorted, wavy reflection.
• Map Lights Not Working (LSi Models): On LSi trims with the map light mirror, the bulbs can burn out, or the switches can fail. This will not affect the mirror's function but will result in a loss of the map light feature. The bulb type for these map lights is a standard #194.

Known Issues, Recalls, and TSBs

There are no specific recalls or Technical Service Bulletins (TSBs) issued by General Motors or the NHTSA for the interior rear view mirror on the 2001-2002 Chevrolet Prizm. The most common reported problem is the mirror detaching from the windshield, which is a universal issue for all vehicles that use a glued-on mounting button and not a defect specific to the Prizm.

Version and Trim Level Differences

Choosing the correct used mirror for your Prizm is critical, as there are two distinct versions that depend on the vehicle's trim and options. This is the most common point of confusion for buyers.

1. Standard Manual Mirror (Base & LSi with Sunroof)

This is a basic, no-frills mirror with a manual day/night flip lever. It has no electrical connections. It is found on all base model Prizms.

• Features: Manual day/night dimming
• Electrical: None
• Part Numbers: GM 94859473 (discontinued); Toyota 87810-01040-C0, 87810-02040, 87810-12210, 87810-12230, 87810-52040

2. Manual Mirror with Map Lights (LSi without Sunroof)

This mirror includes two integrated map lights, one on each side of the bottom of the housing. It is standard on the LSi trim, unless the vehicle has a sunroof. It has a small electrical pigtail that connects to a harness tucked into the front of the headliner.

• Features: Manual day/night dimming, two integrated map lights
• Electrical: Yes, 2-wire connector for map lights
• Part Numbers: GM 94859474

Buying a Used Int Rr View Mirror: What to Look For

Since new OEM mirrors with map lights are discontinued, a used part is often the only option. Here’s how to inspect a used mirror to ensure you get a good one.

1. Verify the Version: First, confirm which mirror your car needs. If you have an LSi, check for a sunroof. If you have a sunroof, you need the basic mirror. If you do not have a sunroof, you need the mirror with map lights.
2. Check the Ball Joint: Hold the mirror base and try to move the mirror housing. It should be firm and hold its position. If it's floppy or loose, it will drift while driving and should be rejected.
3. Inspect the Glass: Check for any cracks, chips, or de-silvering (dark spots) in the mirror glass.
4. Test the Map Lights (LSi Version): If possible, connect the mirror to a 12V power source to test the map light switches and bulbs. If testing isn't possible, assume you may need to replace the #194 bulbs.
5. Match the Color: The 2001-2002 Prizm came with two primary interior colors: Dark Charcoal (a medium-to-dark gray) and Light Neutral (a beige or tan color). Inspect photos carefully to match the plastic housing to your car's interior. Note that new Toyota OEM replacements for the base mirror are now only sold in black.

Step-by-Step Replacement Guide

Replacing the mirror is a simple DIY task that usually takes less than 15 minutes. The only tool required is a T20 Torx driver.

1. Loosen the Set Screw: At the base of the mirror mount against the windshield, there is a small T20 Torx set screw. Loosen this screw a few turns. You do not need to remove it completely.
2. Slide the Mirror Off: With the screw loosened, slide the entire mirror assembly straight up towards the roof. It should slide off the metal mounting button that is glued to the windshield.
3. Disconnect Wiring (LSi Version): If you have the map light mirror, gently pull the wire out from the headliner and disconnect the electrical connector.
4. Install the New Mirror: Connect the electrical harness if applicable. Slide the new mirror down onto the windshield button until it's fully seated.
5. Tighten the Set Screw: Tighten the T20 Torx set screw until it's snug. Do not overtighten, as this can damage the mount.

What If The Mount Fell Off The Glass?

If the metal button itself came off the windshield, you must re-glue it before installing the mirror. You will need a specific rear view mirror adhesive kit, available at any auto parts store.

1. Mark the location of the old mount on the outside of the windshield with a crayon or tape.
2. Use a razor blade to carefully scrape all of the old, dried adhesive from both the windshield and the metal button.
3. Clean both surfaces thoroughly with rubbing alcohol.
4. Follow the instructions on your adhesive kit precisely. This usually involves applying a primer/activator to both surfaces, waiting a minute, then applying a single drop of adhesive to the button and pressing it firmly onto the glass for 60 seconds.
5. Wait for the adhesive to cure completely (check the package, but this is often at least 30 minutes to an hour) before attaching the mirror.
