Problem with my 1997 Buick.
Engine size = 3.3L V6.
Repairs for this problem = A/C compressor, orifice tube and drier replaced about 1 year ago.

A/C is controls are set to max air and max cold on the temp control.

Question We have a 2003 Century Buick. We have had a roaring sound coming from the right rear tire area, but even with tire changes, cannot seem to find the problem. What could be causing this?

How Things Work

Vehicle Front Suspension Operation

The front suspension has 2 primary purposes:

Isolate the driver from irregularities in the road surface.
Define the ride and handling characteristics of the vehicle.

The front suspension absorbs the impact of the tires travelling over irregular road surfaces and dissipates this energy throughout the suspension system. This process isolates the vehicle occupants from the road surface.


Common Engine Codes

Intake Air Temperature Sensor (IAT) Code P0112 Or P0113

The intake air temperature (IAT) sensor is a thermistor which measures the temperature of the air entering the engine. The powertrain control module (PCM) applies 5 volts through a pull up resistor. When the intake air is cold, the sensor resistance is high and the PCM will monitor a high signal voltage on the IAT sensor signal circuit.
