Climate control fan and recirculation

NOTE:

To make it easier to understand, the fault-finding table has been subdivided into three section which concern the three functions also described separately in the wiring diagrams:

Climate control fan and recirculation

Compressor control

Engine fan control

Climate control fan and recirculation

(1) It is possible to replace the bulbs with their bulb holder

(B) Only for fusebox "B"

Compressor control

(*) only up to chassis no. 4065017

(1) Boxer 1.6 e 1.7 16 v, T.SPARK - (2) Boxer 1.3

(* You are reminded that compressor operation is cut off by the system logic under the following conditions:

coolant fluid pressure > 28 bar appr.;

coolant fluid pressure < 2.5 bar appr. (circuit drained);

engine temperature > 111°C (only TD);

full load (temporary cutoff for appr. 8 sec. with engine rpm over 2000 rpm). (only TD).

This operation is also determined by the logic of the ignition/injection control unit (only petrol) (refer to the corresponding sections).
