Does your A/C work sometimes?
Cooling comes and goes, even when you haven’t changed the settings.
- Cold air turns warm during a drive
- Cooling returns after a restart or a change in driving conditions
What could be behind it?
Possible causes.
Possible next steps.
These are examples to help explain the symptom. More than one fault can cause similar behaviour.
Intermittent electrical fault
A connection, sensor or control repair may be needed.
Pressure-related cut-out
Refrigerant or airflow issues may need correcting after testing.
Compressor control issue
Control valve or compressor work may be required if a fault is confirmed.
Inspection confirms what your vehicle needs.
This information is general guidance, not a diagnosis or repair quote. All A/C concerns are subject to inspection and diagnosis. The required work and price can only be confirmed after assessment; none of the repairs listed above is guaranteed to be needed.
A regas does not repair a leak. If a leak is found, we discuss the required repair before recharging the system.
