Here are the most likely scenarios and how to address them:
* Standard, manually adjustable mirror (most common): These mirrors usually attach to the door with a few bolts or screws. You'll likely need to:
1. Locate the access: Look behind the mirror housing itself. There might be small access holes, or you may need to remove the mirror housing completely (often held on by clips or small screws). Consult a repair manual or search online for diagrams showing your specific mirror's removal process.
2. Tighten the fasteners: Once you've accessed the attachment points, tighten the bolts or screws that secure the mirror to the door. A standard Phillips or flathead screwdriver will likely work.
* Power mirror (less common on a 1992, but possible): If you have a power mirror, the process is more complex. The looseness may not be at the mirror's attachment to the door, but rather within the power mechanism itself. You'll likely need to:
1. Diagnose the problem: Is the mirror loose at its base, or is it just flopping around due to a faulty internal mechanism?
2. Access the mirror mechanism: This usually requires more disassembly than a manual mirror. You might need to remove the door panel to reach the motor and gear assembly. This involves removing screws and possibly disconnecting electrical connectors.
3. Repair or replace: The solution depends on the cause. It might involve tightening screws within the power mechanism, or you might have to replace parts of the motor assembly or even the entire mirror.
* Aftermarket mirror: If you have a non-original mirror, the tightening mechanism will depend entirely on the specific design. Consult its instructions or look closely for any visible screws or fasteners.
Important Considerations:
* Repair Manual: A 1992 Jeep Wrangler repair manual (Haynes or Chilton) is incredibly helpful for this type of task. They'll have detailed diagrams and procedures specific to your model.
* Tools: You'll likely need basic hand tools: screwdrivers (Phillips and/or flathead), possibly a socket wrench set, and possibly pliers.
* Safety First: Always disconnect the battery's negative terminal before working on electrical components.
If you're not comfortable with automotive repair, it's best to take your Jeep to a mechanic. Improper repair can lead to further damage or safety issues.
