2004 Saab 9-3 Problem Reports
RepairPal Verified 2004 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.
The thermo contact in the AC compressor can fail, which means the compressor may fail to engage or disengage.
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 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.
