Volvo V70 sunroof leak causing water inside the driver floor on Volvo V70

Some Volvo V70 owners report experiencing issues with sunroof leaks that result in water accumulating inside the driver's floor. These leaks may be attributed to several factors, including cracked window wiper blades that allow water to enter during rain, or clogged drains that prevent proper water flow from the sunroof tray. Additionally, some owners have identified problems with the heater core, even if it has been previously replaced, as a potential source of water pooling. A plugged AC condensate drain line may also contribute to water on the passenger floor, which can subsequently affect the driver's side. Furthermore, issues with sunroof drains and the HVAC system's fresh air intake could lead to water ingress into the vehicle. If the drain is slow or completely clogged, water may travel through the headliner and leak into the driver's side floor. It is crucial for owners to inspect these possible causes and take prompt action to resolve the issue effectively.
