Many Toyota Alphard owners experience air conditioning that isn’t cold.
The first thing many check is the servo motor, but in most cases, that’s not the real issue.
Common causes include:
Front grille gaps are too large,
Small stones hit the condenser while driving,
Condenser slowly leaks gas,
Air conditioning becomes weaker over time.
These problems are hard to notice in the early stage,
and by the time the aircond stops cooling completely, repairing the condenser can be costly.
The correct preventive step:
✅ Install a honeycomb protector in front to reduce stone impact on the condenser.
Air conditioning issues are about proper diagnosis, not just replacing parts.
