Question about 2003 Pontiac Aztek
The All Whell Drive on my Aztek dosen't seem to work anymore, i see ahuge difference when turning and overall driving experience, also seemto use more gaz and have less power, is there any way to know if itsthe computer that no longer activate the rear clutch or if thediferential/clutch no longer work? is it easily reparable, ive done allthe mech on my car so far but the Aztek AWD look weird to me. thanks
Is the AWD light on showing it is disabled? If that is the case, I have the same problem on my 03 and it turned out to be the Rear Wheel Hub(s). $500.00 at a dealer or $129.00 at Auto Zone. Not to difficult to replace, just sits behind brakes and stuff. Another sign if this is your case is that the rear will sound louder that normal, kind of like will sound like that rear has no insulation in it and you can hear everything.

Tips for a great answer:
The AWD data list can be used to assist in determining which type of fault is causing the AWD Disabled Lamp to illuminate. with a scan tool, verify the above data displays are within specification.
AWD temperature disables can be caused by an open circuit.
Using a scan tool, select the Body - Instrument Panel Cluster - Special Functions - Lamp Test mode. In the Lamp Test mode you can turn on or off the instrument panel indicators. All indicators will turn ON when commanded on and OFF when commanded off. The AWD DISABLE indicator should turn on or off as commanded.
If the AWD DISABLE indicator is always ON or always OFF, replace the instrument cluster. Refer to Instrument Cluster Replacement in Instrument Panel, Gages and Console.
The AWD disable lamp illuminates when one of the following conditions exists for 5 seconds:
The PCM commands the solenoid ON and the voltage feedback remains high, B+.
The PCM commands the solenoid OFF and the voltage feedback remains low, 0 volts. This condition is present for 3 key cycles.
The PCM detects fluid temp is too high.
You need to have this hooked-up to a professional grade scan tool.
