SITUATION:

EXCESSIVE FREE PLAY IN FRONT SEAT

The customer complains of fore and aft "rocking" of the complete seat during acceleration or braking.

The condition can occur on either the LH or RH seat. Free play within the power operated seat height adjustment mechanism may be determined to

be the cause.

Improved HVAC Temperature Sensor

AFFECTED VEHICLE RANGE:

Range Rover (LP) Up to 1A450120

SITUATION:

INCONSISTENT IN-VEHICLE TEMPERATURES

The customer may complain of too much heat in cold conditions or being too cold in hot conditions. The in-car temperature sensor is ventilated by a

miniature fan, which draws air from inside the vehicle. The thrust bearing of the fan can wear prematurely, causing the fan to become stiff or

sluggish. The starting torque of the motor is low, permitting the motor to sit in a stalled state. When the fan fails the sensor is not ventilated and the

fascia temperature is sensed instead of the in-car temperature.

RESOLUTION:

REPLACE FAULTY IN-CAR TEMPERATURE SENSOR

NOTE:

The condition described in this TIB is NOT the "32 degree/snowflake" issue dealt with in TIB 80/01/98/NAS and Parts Bulletin PGI99-07. If a

Range Rover HVAC appears to overheat or overcool intermittently and it has the latest head unit, suspect the aspirator.

Where a customer complaint of the above is confirmed, replace the temperature sensor with a new part.

PARTS INFORMATION:

JTF000030 Temperature sensor (includes fan) Qty 1

WARRANTY CLAIMS:

82.20.93 Time 0.60 hrs.

Install replacement fan/sensor assembly

FAULT CODE: D

Normal warranty policy and procedures apply.

Material allowance is included in labor operation.

REPAIR PROCEDURE

REPLACE FAN SENSOR UNIT

1. Use the smoke from an extinguished match or similar source to determine that the sensor motor has stalled.

2. Refer to Workshop Manual, Air Conditioning, section 82.20.93 and perform the fan/sensor replacement repair.
