2001 Mercedes Benz CLK320 6 cyl Two Wheel Drive Automatic 113000 miles
Reguardless if the ignition is on or off the blower for heat and a/c is always blowing on hi. Could issue be related to water leak at base of windshield on passenger side. What is the most likely cause? I'm a licenced mechanic but I'm not familiar with Mercedes (mine, not a customers) I'm generaly a gm and ford guy.
