Saab 93 heater problems

Written by anthony faccenda | 13/05/2017

Founded in 1937, Saab Automobile is a branch Saab AB, which is a Swedish aerospace and defence company. Despite its history of unique design and innovative safety features, Saab is not exempt from mechanical problems. In particular the Saab 900 and Saab 9000 suffer from several heater problems.

Heater Control Valve

A common problem with the 1993 Saab 900 is the heater control valve, which is connected to the heater control levers in the car's interior. The main sign of a faulty heater control valve is not being able to turn the heat on or off. (Reference 2,3)

Heater Fan and Blower

A common problem with the 1993 Saab 9000 is a faulty heater fan and blower resistor, which allows for airflow into the passenger's compartment for the heating system. An indicator of a heater fan/blower in need of replacement is a loud noise coming from the heating unit. (Reference 2,3)


The cost to replace a heater control valve is about £144 for parts and labour. The cost of a new heater fan and blower resistor is approximately £254 for parts and labour as of February 2011. (Reference 2,3)
