Clear Water Leak Under Honda Civic (AC Off)
Clear water leaking from under the vehicle when the AC is off is likely normal condensation from the air conditioning system, but since you noted the AC wasn't running, it could also be rainwater drainage or a minor coolant leak. However, clear water is typically not a critical issue.
Diagnosis Details
Possible Causes
Normal AC condensation drain tube dripping water (even if AC was recently used, residual condensation can drip for a while).
Rainwater or car wash water trapped in body panels or sunroof drains draining out.
Coolant leak (if the fluid is actually clear and slightly sweet-smelling, but coolant is usually colored green, pink, or orange).

What You Should Do
Check the fluid color and smell.
If it's truly clear and odorless, it's likely water.
Verify if the AC was used recently (within 30 minutes).
Inspect the passenger side under the dashboard for dampness (clogged AC drain).
If the fluid is colored or has a sweet smell, check coolant level and look for leaks near the radiator, hoses, or water pump.
