Water drainage relies on:
* Drain channels within the door frames and side sills: These channels direct water to the outside of the car. Blockages in these areas are a common cause of leaks.
* Small weep holes in various seams: These are often difficult to see and are designed to allow for minimal drainage.
* Drainage points near the rear of the car: Water tends to collect towards the rear of the convertible and will drain via specific channels there. These are usually not easily accessible or visible.
If you're having water leakage issues, you'll need to inspect the seals, weatherstripping, and drainage channels along the body rather than searching for specific holes. The locations of potential blockages will vary depending on where the leak is occurring. A professional detailer or mechanic specializing in convertibles will be able to better pinpoint and address the problem.
