Cooling fan at cold start with A/C on

Tags: #cooling-fan · #hvac · #cold-start · #normal-behavior

Symptom raised as a possible concern: at cold start, with climate control set to AUTO (A/C engaged), the engine cooling fan runs for a few seconds and then switches off again — before the engine is anywhere near normal operating temperature ¹². Community answer: this is normal behavior, not a fault. The fan cycling briefly at startup is tied to the A/C compressor engaging, not to coolant temperature; turning off the A/C (or not using AUTO climate mode) during the cold-start/warm-up period stops the fan from cycling this way ³⁴. No repair or diagnosis needed if this is the only symptom — it's a known characteristic of how the climate system interacts with the cooling fan on this car, not a sign the fan or its relay/sensor is malfunctioning.

AC compressor activation on pre-restyle models. To activate the air-conditioning compressor on pre-restyle FAW X80 cars, turn the left rotary dial/knob that controls the AC system — the AC toggles on/off through this interface, rather than a dedicated separate button ⁵⁶.
