Start with the symptom
Notice whether the air is warm all the time, gets cold only while driving, changes with engine speed, or cools on one side only.
Low refrigerant or a leak
Low refrigerant is common, but simply adding refrigerant without finding the leak can leave the underlying problem unresolved.

Airflow problems
A dirty cabin filter, weak blower motor, blocked condenser, or cooling-fan issue can reduce performance.
Compressor or electrical faults
A failed relay, pressure sensor, clutch, compressor, fuse, or wiring problem can prevent proper cooling.
Best next step
A proper diagnosis should measure pressures, vent temperature, compressor operation, and airflow before replacing expensive parts.
