D2: CHECK THE CIRCUIT BETWEEN THE AIR RECIRCULATION FLAP ACTUATOR AND
THE CONTROL PANEL FOR THE CLIMATE CONTROL SYSTEM FOR OPEN CIRCUIT -
VEHICLES BUILT UP TO 08/2004
D3: CHECK THE CIRCUIT BETWEEN THE AIR RECIRCULATION FLAP ACTUATOR AND
THE CONTROL PANEL FOR THE CLIMATE CONTROL SYSTEM FOR OPEN CIRCUIT -
VEHICLES BUILT UP TO 08/2004
Measure the voltage at the air recirculation flap
5
actuator, connector C375, between pin 2 and pin
4, wiring harness side.
Actuate the recirculated air switch several times
6
during the measurement.
Is a voltage of at least 10 V measured with alternating
polarity?
Yes
CHECK the recirculated air flap for ease of
movement and correct operation. If the air
recirculation flap is OK, RENEW the air recirculation
flap actuator. CHECK the operation of the system.
No
Vehicles built up to
LHD vehicles built from
RHD vehicles built from
Ignition switch in position 0.
1
Disconnect Connector C380 from the control panel
2
for the climate control system.
Measure the resistance between the air
3
recirculation flap actuator, connector C375, pin 2
(RHD vehicles: pin 4), circuit 32-FA76 (WH/BU),
wiring harness side and the control panel for the
climate control system, connector C380, pin 14,
circuit 32-FA76 (WH/BU), wiring harness side.
Is a resistance of less than 2 Ohm registered?
Yes
GO to D3.
No
LOCATE and REPAIR the break in circuit 32-FA76
(WH/BU) between the air recirculation flap actuator
and the control panel for the climate control
system with the aid of the Wiring Diagrams. CHECK
the operation of the system.
Measure the resistance between the air
1
recirculation flap actuator, connector C375, pin 4
(RHD vehicles: pin 2), circuit 33-FA76 (YE/BU),
wiring harness side and the control panel for the
climate control system, connector C380, pin 16,
circuit 33-FA76 (YE/BU), wiring harness side.
