What is the color of the substance use a white paper towel and soak some up. Also check your radiator fluid level under the hood, is it full?
Customer: replied 5 years ago.
radiator fluid is full. water leaking on floorboard is clear. appears to be AC condensation due to clogged line. can it be unclogged?
Expert:  JamesH replied 5 years ago.
sorry for the delay internet went down for a moment. Its an issue with the ac drain tube in order to fix the problem you will have to replace the tube also I suggest a flush on the A/C since the tube is clogged it could be pretty ugly in the system. Thanks
