1. Interior Access (Most Likely Solution):
* Locate the Latch Mechanism: The tailgate latch mechanism is usually found inside the vehicle, on the rear panel just above the tailgate. It's often covered by a trim panel or carpet. You'll need to carefully remove this trim to expose the latch mechanism.
* Look for a Release Rod or Cable: Once the trim is removed, examine the latch mechanism closely. There might be a small rod or cable connected to the electric release. You might be able to manually manipulate this rod or cable to unlatch the tailgate. This often requires some careful probing and pushing/pulling. A long, thin object like a coat hanger might help.
* Direct Manipulation: In some cases, you might be able to reach parts of the latch mechanism and manually depress the latching mechanism itself.
2. Exterior Access (Less Likely, More Difficult):
This method is more challenging and risky, potentially causing damage. Only attempt this if the interior method fails.
* Access from Under the Vehicle: Get underneath the Blazer and try to see if you can reach any part of the latch mechanism. This is very difficult and may not offer any solution.
Important Considerations:
* Trim Removal: Be extremely cautious when removing interior trim panels. Use plastic pry tools to avoid scratching or breaking the plastic. Refer to a repair manual for your specific Blazer model if you are unsure how to remove the panels safely.
* Safety: Always support the tailgate while attempting to open it. It's heavy and could cause injury if it falls unexpectedly.
* Repair Manual: A repair manual specific to your 1996 Chevy Blazer is highly recommended. It will show you diagrams of the tailgate latch mechanism and the best way to access it.
If you are not comfortable working on your vehicle yourself, it's best to take it to a mechanic. Attempting to force the tailgate open could cause damage to the latch mechanism or other parts of the vehicle.
