Newest 2006 Saab 9-3 Problem Reports
The air blend system in the heating, ventilation and AC (HVAC) system can have problems, which can cause the AC controls to be stiff, or a lack of HVAC control.
The anti-lock brake system (ABS) and/or traction control light may illuminate. This can be caused by corrosion in the (ABS) wire harness connector at the right front wheel speed sensor due to water intrusion. Corroded connectors should be cleaned or replaced as necessary to correct this concern.
When trying to close the window, the window glass will drop a few inches after reaching the closed position.This can happen on any window that has the automatic closing feature.
The system that prevents you from being injured by the automatically closing windows is called the "pinch protection system" and this system needs to be reset, reprogrammed or is defective.
In your owners manual you will find instructions on how to reset this feature. If that doesn't work, you'll need a Saab repair shop or Dealership to check for a software update for the pinch protection system, or see if there is a defective part. Have the shop reference the Saab Technical Service Bulletin (TSB #831-2639)to help address this issue.
A high or low beam failure may be indicated on the instrument panel display even though the lamps are working properly. Our technicians tell us reprogramming the control module with upgraded software may remedy the 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.
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.
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.
