AC Condensation Drain Leak
Clear water leaking from under the vehicle while the AC is running is normal condensation from the air conditioning system. The evaporator collects moisture from the air, which drains out as water. This is not a mechanical issue.
Diagnosis Details
Possible Causes
Normal AC condensation drainage – the evaporator core removes humidity from cabin air, producing water that exits via a drain tube.
Clogged or partially blocked AC drain tube causing water to overflow from the drain pan or exit from an unusual location.
