Cabin & comfort

Absorbs cabin-air heat as refrigerant evaporates.
Inside the dashboard HVAC housing.
Air passing over the cold surface loses heat and moisture; condensate drains outside.
The cold indoor coil in a refrigerator.
Weak cooling, odors or interior water can involve refrigerant faults, contamination or drains.
Filters use the service schedule. Motors, controls, seals and trim are inspected for condition and operation.
A filter or switch service differs from dashboard removal or a complete seat mechanism; access can be the main expense.
Water dripping under a BMW after air-conditioning use can be normal condensate, unlike a coolant leak.
BMW cabins as equipped; controls and comfort hardware vary substantially by generation.
