BYD Sealion 7 Cabin Air Conditioning and Thermal Checks

State sun or shade, ambient and cabin temperatures, soak time, state of charge, doors, windows and passenger load. A pre-cooled showroom car is not comparable with a vehicle parked outdoors.

Test fan speeds, vent selection, recirculation, temperature commands, demist and rear-cabin outlets. Record slow actuators, clicking, intermittent screens, odor, weak zones and drainage.

Compare stationary climate use, low-speed traffic and a steady safe road segment. Record power demand, estimated range movement, warnings and any loss of cooling or heating under load without promising a fixed range effect.

Check accessible filters, intakes, condenser area, drains and leakage evidence. Preserve diagnostic faults before clearing. Refrigerant and high-voltage compressor work belongs to trained personnel.

A comfortable cabin does not prove battery, inverter or motor cooling health. Review applicable temperatures, fans, pumps, heat exchangers, charging behavior and faults as separate evidence.

Confirm refrigerant procedure, diagnostic access, filters, actuators, blowers, condenser and high-voltage climate components for the exact market version, including parts lead time.

Close this specific file by placing soak and cabin-temperature record, control and airflow map and road and energy-use observation in one dated candidate record. The reviewer should be able to confirm that test conditions are reproducible and that cabin and battery cooling are not conflated. Name the person or provider responsible for every unresolved point, add a realistic cost or consequence, and state what evidence will change the decision. If the VIN, version, condition or destination basis changes, reopen this file instead of carrying the previous conclusion into a different purchase.

A useful decision records what is verified, what remains seller-stated and what was not tested. Attach a consequence and owner to each open item. Do not let a broad assurance replace a missing VIN record, charge test, condition image or destination opinion. Acceptance should be explicit: proceed, proceed with a priced condition, obtain more evidence, or reject. A replacement VIN never inherits an earlier acceptance.

Give images, scans, diagnostics and quotations a date, source and vehicle identity. Preserve originals before translation or editing. If custody, software, repair, route or candidate changes, identify which conclusions expire and repeat the affected checks instead of silently carrying them forward. Before inland release, read the same identity, propulsion, value and parties across contract, invoice, inspection and shipping drafts. Registration and customs remain separate destination checks.
