Here's a breakdown of what could be wrong and why you should likely seek professional help:
* Clogged Retractor: The most common cause. Dirt, debris, or rust can jam the internal workings of the retractor mechanism, preventing it from releasing. This often requires disassembly, cleaning, and potentially lubrication (using a *specific* lubricant designed for this purpose – NOT WD-40).
* Broken Spring or Gear: Inside the retractor is a spring and a gear system. These can break or wear out, rendering the retractor inoperable. Replacing these parts typically requires significant disassembly and specialized tools.
* Binding or Damaged Belt: The shoulder belt itself might be twisted, frayed, or snagged, preventing it from retracting smoothly. Inspect the belt closely for damage. A severely damaged belt should be replaced, not just lubricated.
* Damaged Latch or Mounting: The harness's mounting points or the latch mechanism itself could be broken or improperly aligned.
Why you shouldn't DIY (unless you're experienced):
* Safety Critical: Seatbelts are crucial safety devices. Improper repair could lead to a malfunctioning seatbelt in a crash, potentially resulting in serious injury or death.
* Complex Mechanism: The retractor is a complex piece of engineering. Disassembling it without the correct knowledge could cause irreversible damage.
* Potential for Injury: Springs under tension in the retractor can cause injury if released unexpectedly.
Recommended actions:
1. Safety First: Do *not* attempt to force the belt. This could damage the mechanism further.
2. Professional Repair: Take your Camry to a qualified mechanic or an automotive upholstery shop specializing in seatbelt repairs. They have the expertise and tools to diagnose and fix the problem safely and correctly.
3. New Retractor: The most likely outcome is that the retractor needs to be replaced. This is often a cost-effective solution, considering the safety risks involved.
In short, while the underlying cause *might* be simple, the repair is not. Prioritize safety and seek professional help. A working seatbelt is paramount.
