I own a 2006 Volvo s40 t5 AWD that is leaking water into the front passenger foot well. I have determined after trouble shooting the problem that it only leaks when it’s raining and I have the climate control (heater) engaged. It does not leak when it’s raining and the climate control is off. I’ve pulled the front rug insert and can see a small drip coming from under the dash. This is not a leaky sunroof issue. Has anyone experienced this issue before?
