2003 Pontiac Aztek Q&A

2003 Pontiac Aztek Question: Aztek AWD and anti-lock break light

Aztek awd, AWD disable and anti-lock break light are both on as soon as I start the car and remain on. Ive replaced all four wheel bearing/ hub assembly, they where all bad, I know these vehicles are notorious for them. Any ways just wondering if any one has had this problem and how to fix it. Also when applying the break at a very slow stop, the break pedal makes a flutter/ pulsating feeling and I can hear a clicking noise coming from out side the vehicle. Any advise would be helpful. -
Answer 1
Scan test of the ABS will reveal which wheel speed sensor(s) need to be replaced or the circuit(s) checked. Both lights are indicative of this problem! VERY possible a sensor or wiring to the sensor was damaged on install of the bearings. -

That makes a lot of sense, do you know the best place to have it scanned? Im sure auto zone doesnt have the ability to do it. Also thanks for the advice. -
Comment 2
Well, any shops around town there with a mechanic everybody knows and recommends? You're right, Zone, or other parts stores, can't do a real test but a REAL scanner will show where the problem is quickly! Any shop with say a Snap-On Modis scanner of equivalent can do this. Fact of the matter is if YOU had a Modis, you could find the problem! They are that easy to use and that good, just very expensive! -

You're welcom. Without a scanner, it's just a guessing game! If you locate a shop that has one and the user can read, this is a walk in the park on a sunny day! -
Comment 5
Yeah and the guessing game always cost a lot of money. Lol which is why I got on here and asked opinoons first. Wish me luck, im hoping for a walk in the park on a sunny day kinda repair. -

You got it. So many post on here where folks just throw parts at their vehicle without any testing. 95% of the time, testing would have saved them money!! Then they start asking questions. There is CHEAP but no such thing as inexpensive anymore, so smart move on your part, let us know how it comes out. -
Answer 2
The AWD disable light is a common Aztec problem. After talking to a mechanic and having my car checked out he said that the AWD still engages and the fix for the malfunctioning sensor isn't cheap so I should not waste my money. As for the anti-lock breaks, I took my car in and paid big money to replace the module which the mechanic (different mechanic) said would fix it. Said he sees it all the time... it didn't work. The wiring harness (very cheap in comparison) was then replaced which fixed it for me. All that and only one tire was showing the problem. Oh well. I hope this helps! -
