UCH
(continued 2)AC016:RCH no. 1 relay. Commands for testing the
operation of the RCH
(passenger compartment
air heating resistors). The
number of RCH stages
switched on depends on the
number of relays actuated.
NOTE: RCH no. 3 relay is
only fitted to Mégane
Scénics.If there is a fault, refer to the
fault finding procedure
for these controls.
NOTE: To find the relays
