Read off / program the blower fan run-on (Electronic climate control, Manual climate control)

Hint: In certain circumstances it may be necessary to allow the blower fan to run on. This dries the evaporator and prevents bad odors which can otherwise be caused by residual water in the system.




- Ignition on
- Use the Programming function for to read off and program blower fan speed compensation. For further information about programming, see Diagnostic functions Diagnostic Functions.
Read off the programmed value and compare with the programmable values below.
- 0 = No run-on
- 1 = Run-on (default value).
Program as necessary.





Were any changes made?

Yes - Fault Found

No - No Fault Found
