I have hot water leaking down into the driver side of a '97 T and C 3.3 liter. I had the heater coil replaced a couple years ago after it blew and when this happened before it was clogged drain tubes. Can this be related to a bad evaporator purge solenoid or is it just the tubes clogged again? Thanks!

The evaporator purge solenoid has nothing to do with the heater. I would say the heater core has gone away again and will need replaced if the water you describe is coolant. If it is fresh water then clean out the drain again and it should go away.

if it's the heater core that went, he would be getting water on the passenger side
