OWNER ANSWER
Where is the fan speed control on the BYD DOLPHIN SURF?
Open the full A/C screen and use the blower speed control. It is separate from the temperature controls. If the bottom bar only shows temperature, use the full A/C screen to adjust the fan.

For the DOLPHIN SURF with the A/C screen shown in BYD’s 07.2024 EN_V0 right-hand-drive handbook. Shortcut layouts can differ by software.
- While parked, open the full A/C screen and switch the system on if needed.
- Find the blower speed adjustment, control 11 in the handbook diagram. Tap a higher or lower level.
- If the fan responds, use that control when the shortcut is missing. Owners reported two linked temperature shortcuts and changes to the fan shortcut after updates. The handbook gives no procedure for removing a temperature shortcut.
What success looks like
The displayed fan level changes and airflow increases or decreases.
If that did not work
If the full panel works but the shortcut is missing, ask BYD which shortcuts your software supports. If airflow does not change, report the selected levels, what the display showed and your software version. Ask BYD to check the climate controls and blower operation. If the windscreen cannot be kept clear, stop safely and use the linked demisting checks.
