Clear Water Leak Under Nissan Rogue (AC Off)
Clear water leaking from under the vehicle when the AC is not running is likely condensation from the air conditioning system or possibly rainwater from the cowl area. Since the AC was off, it may be residual condensation or water from the evaporator drain. This is typically not a mechanical issue.
Diagnosis Details
Possible Causes
Residual condensation from the AC evaporator drain tube (common even after AC is turned off)
Rainwater or car wash water draining from the cowl or sunroof drains
Coolant leak (unlikely as coolant is usually colored and sweet-smelling, not clear water)
