Solution

1. Preparation

Gather necessary tools and materials.
Tools Required:
- Compressed air or a wet/dry vacuum
- Soft brush or pipe cleaner
- Bucket or pan to catch any water
Safety Warnings:
- Ensure the engine is turned off and the vehicle is in park with the parking brake engaged.

2. Locate the AC Drain Line

Position the vehicle on a level surface and raise it using a jack if needed.
Locate the AC drain line, which is typically found on the passenger side of the vehicle, near the firewall.

3. Clear the Blockage

Using compressed air, gently blow into the drain line to dislodge any blockages.
- If using a wet/dry vacuum, connect it to the drain line and create a seal to suck out debris.
If the blockage is stubborn, use a soft brush or pipe cleaner to carefully remove any obstructions from inside the line.

4. Test the Drain Line

Pour a small amount of water into the AC drain line entrance to ensure it flows freely out of the exit point under the vehicle.
Observe for any leaks or blockages during this test.

5. Reassemble and Clean Up

Replace any covers or components that were removed during the process.
Clean any spilled water and check the passenger compartment for any signs of moisture.
