Repairpal verified Saab 9-3 problems
If the battery "goes dead" after sitting for several hours, but only when key is left in the ignition, in the "off/lock" position. The problem may be with the stereo amplifier staying on. Our technicians tell us reprogramming the affected control module can remedy this problem.
Slow or sluggish gearshift operation may be noted on vehicles equipped with a six speed manual transmission. Our technicians remind us it is important to ensure the correct Saab approved gear oil is used. Also, Saab has revised the fill capacity from 3 liters to 2.4 liters to help address this concern.
Code C155037 (control module internal fault) may set in the steering control module due to low battery voltage. Our technicians recommend a complete inspection of the starting and charging systems before replacing the steering control module for this fault.
The third brake light and/or license plate lamp may fail due to wiring damaged from rubbing on the trunk lid handle. Our technicians tell us the repair involves correcting the damaged wiring and isolating the connectors so they do not contact the trunk lid handle.
A higher than normal idle speed may result in harsh transmission engagement from park to drive and/or reverse. Our technicians tell us that adjustment and reprogramming the engine idle speed should resolve this issue.
A knocking noise while turning and/or a banging noise when driving on rough roads may develop in the front suspension. This type of noise is commonly caused by a front strut thrust bearing damaged due to water intrusion. Our technicians tell us revised thrust bearings are available to correct this concern.
The shaft for the air blend door can fail creating the inability to adjust the AC or heating temperature. The AC or Heat will not maintain the proper temperature.
The air conditioning expansion valve can fail causing poor, or no cooling from the AC system.
The fuel pump check valve may have failed if the engine requires more cranking before it starts. The check valve is a one way valve that maintains the pressure in the fuel lines so the engine is easier to start after it has sat a while.
If the engine will crank but not start, it may be the fuel pump has failed. Diagnosis may find no fuel pressure when attempting to start the engine.
