Taken from TSB No. 24/1999 13.04.2000
Should a customer express concern about poor interior ventilation and misting of windshield, door windows and rear window, the probable cause is insufficient forced air extraction in the area of the rear bumper, combined with insufficient blower motor power. To rectify this concern, install a modified cover on the forced air extractors, remove part of the bumper padding to improve the air flow rate and install a modified blower motor resistor.
Note:
After reworking the vehicle as described in this bulletin, make sure that the customer is fully conversant with the operation of the temperature and air distribution controls, as described in the Owner's Guide.
Parts Required:
Forced air extraction cover (two off) ..4043548 NOW 1573138 @ £6.48 Each plus vat
Blower motor resistor ......................1110969 NOW 1311115 @ £16.63 plus vat
Anyone heard or know of this issue?
