Removing/installing and checking fresh air blower series resistor with overheating fuseN24 - heater, manually controlled air conditioner

Removing/installing and checking fresh air blower series resistor with overheating fuse -N24- - heater, manually controlled air conditioner

Note

t	The resistance value between contacts 2 and 4 of -N24- is approx. 1.8 ohms (between contacts 3 and 4 approx. 0.7 ohm and between contacts 1 and 4 approx. 0.1 ohm).

t	Upstream of contact 4, -N24- is fitted with a temperature-sensitive fuse which is tripped in the event of a fault at the fresh air blower -V2-.

WARNING

Risk of burns.

t	The fresh air blower series resistor with overheating fuse -N24- may be hot.

t	Allow the series resistor to cool down prior to removal.

Removing

–	Remove the glove compartment → Rep. gr.68.

–	If applicable, remove the headlight range control unit → Electrical system; Rep. gr.94.

–	Sever the cable tie at the fresh air blower.

–	Turn the series resistor -4- in -arrow direction- and lift out.

–	Take out the series resistor between the air duct -1- and the central tube -2-.

–	Unplug the connector -3-.

Installing

Install in reverse order, paying attention to the following:

–	Fit the headlight range control unit → Electrical system; Rep. gr.94.

–	Fit the glove compartment → Rep. gr.68.
