1989 Saab 900 or 9000 Series - Dead Battery

At times, 1989 Saab 900 and 9000 Series cars (Bosch p/n AL69X, AL129X, and AL54X) can experience dead batteries. Before checking the charging system, look at the part number on the radiator fan time-delay relay! Radiator fan time delay relay (p/n 95 63 339) is prone to sticking closed, which will cause the cooling fan to run longer than the 10 minute cool down period, thus discharging the battery. If the vehicle in question is equipped with one of these relays, replace the relay with p/n 85 22 10.
