2025-2026 Chevrolet Blazer EV Overhead Console: Sunroof Faults and Option-Specific Failures

Key Failure Symptoms

Failures in the Blazer EV's overhead console are typically electrical. Given the vehicle's recent introduction, many issues may be related to software glitches or early production faults rather than long-term wear.

1. Sunroof Opens Immediately After Closing

A known issue for the 2024-2025 Blazer EV involves the sunroof reversing and opening on its own right after it has been closed. This is often a sign of a problem with the sunroof's position sensor or logic, which is controlled via the overhead console switch. General Motors has issued an Engineering Information (EI) document (PIE0795) to investigate this specific problem. The system may require a reset, which can sometimes be triggered by multiple failed closing attempts.

2. Unresponsive or Intermittent Switches

The most common symptom of a failing console is when the buttons for the sunroof or garage door opener stop working entirely or only work sporadically. This can be caused by a failure in the switch mechanism itself or, more likely, a problem with the internal circuit board or electrical connector. On other vehicles, failed solder joints on the circuit board are a common cause of this issue, often due to heat cycles.

3. Interior Lights Not Working

If the map lights or courtesy lights housed within the console fail to turn on, it could point to a burnt-out bulb, a faulty switch, or a loss of power to the console itself. In some cases, a failure within the console's circuit board can affect multiple functions at once.

4. Rattling or Loose Fit

The console is primarily held in place by plastic and metal clips. If these clips break during a previous repair or due to vibration, the console can become loose and rattle against the headliner. This is often first noticed when driving over rough roads.

Buying a Used 2025-2026 Blazer EV Overhead Console

Since the Blazer EV is a new model, the market for used parts is just beginning. However, buying a used OEM console can be a cost-effective solution if yours fails. Here’s what to inspect:

• Verify the Part Number: The most critical step is to match the part number. Look for 85692787 on the part label. This ensures electronic and feature compatibility.
• Inspect All Mounting Clips: Carefully check all plastic tabs and metal clips around the console's perimeter. These are essential for a secure, rattle-free installation. If even one is broken, the console may not sit flush against the headliner.
• Check the Buttons: Press each button (sunroof, garage door opener, lights). They should have a solid, tactile click without feeling sticky or loose.
• Examine the Lenses: Ensure the plastic lenses for the map lights are not cracked, hazed, or yellowed.
• Look for Water Damage: Check the housing and electrical connectors for any signs of corrosion or water stains, which could indicate a leak from the windshield or sunroof and suggest hidden electrical problems.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no recalls specifically for the overhead console itself, several issues with the Blazer EV are relevant.

• NHTSA Recall 25V433 (GM N252503010): Affects some 2024-2025 Blazer EVs for a rear parking brake wiring harness that can become damaged, potentially causing the parking brake to activate while driving or fail to hold.
• NHTSA Recall for Door Strikers: Some 2025 Blazer EV models were recalled because the door strikers were not properly heat-treated and could break.
• GM Engineering Information PIE0795: This bulletin was issued to gather data on vehicles where the sunroof opens by itself after being closed, a function directly tied to the overhead console switch.
• General Electrical Glitches: Early owners and reviewers have reported numerous software and electrical issues with the Blazer EV, from infotainment screen failures to unresponsive controls.

Replacement Cost & Difficulty

Replacing the overhead console is a straightforward job suitable for most DIY mechanics.

Installation Difficulty: 1/5 (Easy)

Estimated Time: 0.5 hours

The process generally involves using a plastic trim removal tool to carefully pry the console down from the headliner, starting from the edge nearest the windshield. Once the clips release, there will be one or more electrical connectors to unplug before the unit is free. Installation is the reverse of removal.
