Attention! Depending on the configuration, the car can be equipped with a heater with or without air circulation mode in the cabin. A heater with recirculation mode can be recognized by the presence of a switch with a corresponding icon on the panel. This mode, for example, can be turned on when driving through a tunnel or when driving in an area with an unpleasant odor. In this case, the air pumped into the cabin by the fan will be taken from the cabin, and not from outside. The procedure for dismantling the fan electric motor depends on the type of heater.
Removal
1. Heater with air recirculation mode in the cabin. Turn on the heater to the air intake mode from outside. The fresh air intake cover should not be closed,
2. Remove the fairing cover, see the relevant chapter.
3. Remove the air intake.
4. Disconnect the negative (-) battery terminal.
Warning! This will delete data from memory devices, such as the radio's security code. Before disconnecting the battery, read the recommendations in Chapter "Battery - removal and installation".
