AC Only Cools While Driving
The car AC cools well while driving on the road but weakens or stops cooling when idling or in traffic.
Possible Causes
Condenser Fan Not Working
High likelihoodThe fan that cools the condenser at idle is not working. While driving, natural airflow compensates.
Slightly Low Refrigerant
Medium likelihoodRefrigerant is slightly below the required amount, showing weakness at low airflow.
How to Diagnose?
- 1 Turn AC on at idle and check if condenser fan spins
- 2 Inspect condenser fan fuse and relay
- 3 Measure refrigerant pressure at idle
- 4 Check condenser cleanliness

Frequently Asked Questions
Why does AC weaken only in traffic?
At idle, no natural airflow reaches the condenser. The condenser fan does this job, and if it's faulty, cooling weakens.
