Possible causes.
Possible next steps.
These are examples to help explain the symptom. More than one fault can cause similar behaviour.
Contamination or moisture
Cleaning or drain attention may be appropriate after checking the cause.
Dirty cabin filter
A contaminated filter may need replacement.
Another source in the vehicle
Inspection may identify a source outside the A/C system that needs separate attention.
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.
