Reference Number(s): 870-2020, Date of Issue:  September 1998
SAAB: Cars without ACC
MARKET: All

SUBJECT

Problems adjusting heating

Fig 1: Control Panel
G00416195

CARS AFFECTED

All cars without ACC within VIN intervals:

  1. W2050001 - W2053455

    and

  2. X2000001 - X2002512

BACKGROUND

The heater temperature control cable on certain cars within the above VIN intervals could be bent or broken. This may be caused by a stiff air blending flap (heater shutter), insufficient clearance between the cable loop at the end of the cable and the pin on the lever, low safety margin (materials too close in tolerance) or a restriction in the cable sheath.

Various measures have been taken in production to solve this problem, which means that cars with VIN from W2053456 and X2002513 respectively are correct.
