1. Cable Issues:
* Broken Cable: The most common culprit is a broken or frayed hood release cable. This often occurs near the latch mechanism or where the cable bends sharply. You'll need to visually inspect the cable's entire length, both inside the car and under the hood (if you can safely access it). You might need to remove some interior panels to get a good look.
* Cable Disconnected: The cable might have come loose from either the release lever inside the car or the latch mechanism under the hood. Check both ends for proper connection.
2. Latch Mechanism Problems:
* Latch Sticking: Dirt, debris, or corrosion can prevent the latch from releasing. Try lubricating the latch mechanism with a penetrating lubricant like WD-40 (but be cautious around electrical components). You may need to use a long, thin object to carefully work the mechanism free if it's seized.
* Latch Broken: The latch itself might be broken or worn out. This would require replacing the latch assembly.
3. Release Lever Issues:
* Broken or Loose Lever: The internal mechanism of the release lever inside the car could be broken or improperly connected. This would require checking for any internal damage or loose parts.
4. Other Potential Issues (Less Likely):
* Vacuum Leak (If applicable): While less common on a 1990 Corvette, some models might have a vacuum-assisted release. A leak in the vacuum system could prevent it from working.
* Wiring Problem (If Electric): While most 1990 Corvettes use a purely mechanical system, a very rare possibility of a secondary electrical component could be at fault.
Troubleshooting Steps:
1. Visual Inspection (Inside): Carefully examine the hood release lever inside the car. See if it feels loose, if there's any obvious damage, and if it moves freely.
2. Visual Inspection (Under Hood - If Possible): If you can safely access the hood latch mechanism from underneath (perhaps with the help of a friend or by slightly lifting the hood with a tool), examine the latch and cable for damage.
3. Lubrication: Apply a penetrating lubricant to the latch mechanism.
4. Check Cable Connections: If you can safely access the cable ends, check both ends for proper connection and firmness.
If you are not comfortable working on your car yourself, it's best to take it to a qualified mechanic. Improperly handling the hood latch could lead to injury. They will have the tools and expertise to diagnose and repair the problem efficiently. They can also easily identify if the problem is something more than just the simple cable or latch mechanism.
