An exterior louver is installed upside down and catches rain
Exterior louver blades and drainage paths are directional. If the louver catches rain, stop and reset it to the approved orientation before the wall is closed or weather hits.
Do not caulk over an upside-down louver and hope the sealant fixes the water path.
Check
Check blade slope from the exterior side.
Verify the sill, gutter, and weep holes are at the bottom/outside.
Look for water tracks inside the sleeve or mechanical room.
Confirm orientation against the submittal or manufacturer label.
Reset and reseal before siding, stucco, or trim hides the frame.

Say this to your foreman
The louver at [location] appears upside down and is catching rain. I checked the blade slope and weep path. Do you want me to pull it and reset it to the manufacturer orientation before it gets covered?
