I think that the ABS TRAC OFF light has more to do with the ABS sensors not giving reliable speed or movement information to the ABS Control Module. Harness connections or broken wires to the module can cause the same problem, or the hub assembly ($49 to $79 to $109 for the part) may have to be replaced to start with.

The driver door window switch not functioning correctly may be a bad or dirty switch which can be obtained from a salvage yard for a lower price than from the dealer. I would test the switch current before replacing, though, with a test light to ensure the wiring is not an issue with this circuit, as well.

Good luck on these repairs on the 2005 Buick Century.

    I would take the vehicle back to the dealer, then contact the district and regional managers for the dealer to see if there is a dealer solution to the problem.

ABS, TRAC OFF, SERVICE VEHICLE SOON LIGHTS ARE ON. BRAKE PEDAL PULSATES INTERMITTENLY AND MAKES NOISE.

with these lights on then you will have to see what codes are in the abs and pcm module to find out what the problems are.the abs module will activate when the traction control lights come on.this can also cause a noise and pulsate in the brakes pedal.

Abs light, trac off light,and vehicle service soon comes out

Guys i have a 2001 buick century. i ran into that problem figured for sure it was a wheel sensor but it wasn't if you can get a friend with a scanner to pin point which wheel it is then you're half way there. you said when you turn the wheel the light comes on well you know it one of the front wheels for sure, i was with my brother one of us was looking at the dash and the other was moving around the connector to let the other know when the light came on lots of posts spoke about the wires breaking at the point where they bend that wasn't the case. sure enough it was the wires going into the connector as you turn the wheel left and right the wire looses contact for a fraction of a second causing the abs light to come on. so check the connectors at each wheel under the cv joints.
hope this helped
good luck guys

Trac, Abs and Service engine light on - 2001 buick Century

The ABS system including pump may be faulty which is quite common. You will have to take this to dealership or mechanic. Either there is a bad pump or a fault in the electrical system

Buick century trac off light come on and abs light

i solved this problem earlier in this site if you search it youll see my essay, but basically you just have to change the abs cable (drivers side), you can get it from any GM vehicle, cut the cable from about 30 centimeters from breaks and replace

Dome lights won't go out / 93 buick century

your doorswitch is inside the door on the striker latch. You will need to remove the door panel to access. chances are it is stuck in the closed position. Your seatbelt latch sensor has also gone bad. It is located inside the receptacle of the seatbelt. If you only want to diengage the light, look for the molex plug attached to the wire coming from the seatbelt receptacle.

ABS/SERCICE ENGINE SOON/TRAC OFF LIGHTS ARE ON

Are you sure of the lights? If it is Service VEHICLE Soon, in addition to Trac Off and Anti Lock, it is most likely one of the four wheel hub assemblies. These are sealed bearing units that feed a signal to the computer for the ABS brakes and the tire pressure system. I had one go out intermittently (seemed to be aggrivated by humidity/moisture). I had it replaced, and another one is going out. It seems like they are a bit prone to failure. My Century has 101K, and I experienced the first one around 75K miles. Unfortunately, to tell which one is failing requires a scan tool above and beyond the simple one that most parts stores use. BTW, there was a problem that was fixed just prior to 2002 that was caused by the signal wires going to the left front wheel hub being worn through and shorting. I believe this problem was fixed by 2002.
