Fixing Water Leak on Passenger Side – Toyota HiAce (Clogged AC Condensation Pipe)
Look under the passenger footwell area.
Locate the plastic cover beneath the glovebox area.
Remove the star clip on the left side of the cover.
You can use a screwdriver or even a butter knife to pop it off.
Take off the cover to expose the components behind it.
Find the AC condensation pipe (this is usually the cause of the leak).
Pull the pipe off from its connection.
Blow into the end of the pipe to clear debris.
You should hear or see dirt/water discharge as it clears.
Once clear, reconnect the pipe by pushing it back into its original fitting.
Reinstall the plastic cover:
Line up the clips.
Push the cover back into place.
Reinsert the star clip to secure it.
This should stop the water leaking into the passenger footwell.
