Weak Airflow
Reduced vent output can come from a clogged cabin filter, failing blower motor, blocked evaporator, or blend-door problem.
Recharge Does Not Last
If cold air only returns for a short time after recharge, the system likely has a leak that needs to be found and repaired.
AC Compressor Not Engaging
Compressor clutch fails to activate from low refrigerant, faulty relay, or electrical issues.
Refrigerant Leaks
Visible oil residue or UV dye indicates leaking hoses, connections, condenser, or evaporator.
AC Cycles On and Off
