Car AC Repair Diagnosis Tool
Is your AC blowing air at all?
Is the air cold?
Do you hear the fan when AC is on?
Low Refrigerant Suspected
Your AC system may be low on refrigerant. A recharge or leak test may be needed.
Blower Motor Issue
Weak airflow can point to a failing blower motor or a clogged cabin air filter.
Compressor or Refrigerant Issue
The fan is working, so the issue may lie with the AC compressor or low refrigerant levels.
Blower or Electrical Issue
If the fan isn’t running, you may have a blower motor failure, blown fuse, or electrical issue.
