1. Identify the Source (Crucial):
Before doing anything, find out *where* the moisture is entering. Is it a small leak around the seal, or is there a crack in the lens? This will determine your repair strategy. Carefully examine the headlight housing, looking for any visible cracks, gaps, or damage to the sealant.
2. Temporary Drying (Short-Term Solution):
* Use a dehumidifier: Place a small dehumidifier near the headlight(s) if you only need a temporary solution. This pulls moisture from the air, potentially reducing condensation inside the housing.
* Rice: This old trick has mixed results, but you can try placing bowls of uncooked rice inside the headlight housings (if you can safely open them). The rice absorbs moisture. *Do not use this method unless you can easily open the headlight housing.*
3. Long-Term Solution: Repairing the Leak
This is the only way to permanently fix the problem. It usually involves:
* Professional Repair: The best approach is to take your Durango to a qualified mechanic or auto body shop. They have the expertise and tools (like a heat gun for resealing) to properly address the leak. They can identify the source, reseal the housing, and possibly replace the seal.
* DIY Repair (Advanced, Risky): If you're experienced with auto repairs, you *might* attempt this yourself, but it's more challenging and requires specific tools and knowledge. This generally involves:
* Disassembling the headlight: This is tricky and could damage the headlight if not done carefully. You'll need to remove the headlight assembly from the vehicle.
* Cleaning the housing: Thoroughly clean the inside of the housing and the gasket.
* Replacing or resealing the gasket: This requires the correct gasket and possibly a sealant to ensure a watertight seal. Improper sealing will just lead to the problem recurring.
* Reassembling the headlight: This must be done carefully to avoid damaging any components.
Important Considerations:
* Warranty: If your Durango is still under warranty, contacting the dealership is crucial. They'll handle the repair without costing you anything.
* Safety: Driving at night with impaired headlight visibility is dangerous. If the moisture significantly impacts your vision, avoid driving until the issue is resolved.
In short: Don't just try to dry out the headlights. Find and fix the leak. A professional repair is usually the best and safest option for a lasting solution.
