Well Carol, to be quite honest, your problem is not easy to DIY and it probably won't be super cheap to fix. The "Trac OFF" light indicates that the Traction Control is not on or not functioning properly. This usually means that the TCM or Traction Control Module is bad. The "Anti Lock" light indicates that you most likely have one or more wheel sensors that are bad, or the ABS (Antilock Breaking System) has a bad module. You may also want to check out some forums on the buick century. It seems as thought the problems you are experiencing, are quite common in the Buick Century. Here are a few links that may help you narrow it down and possibly find a manufacturers recall on the problem. Hope this helps.

One of the wheel speed sensors are bad. It is hard to tell which one it is without a scan tool. You might be money ahead to have a shop with a scanner tell you which sensor is bad if you don't own a scanner. It needs to be driving with a scan tool on it while watching the speeds of the wheels. The one that is bad will read different than the rest at slow speeds.

Service vehicle soon, anti-lock, trac off all on

You need a new wheel bearing, This also happened to my olds alero, make sure 2 jack up each tire 1 at a time and pull back and forth on them checking for play, once you have found the 1 that has play or wobbles that is the 1 that needs a new wheel bearing

Brakes lock on ice, snow, rain, and high temperatures

Sounds like your Anti lock brake valve is not functioning right. The bad thing is that it has to be serviced by a technician. When they lock up is there any lights on the dash that light up like something that says anti-lock?

Break light....

There's a switch on your emergency brake that the indicator (on your dashlight) operates from. Sometimes it slips in its bracket and gets out of adjustment causing your dash light to stay on. Its located on the upper part of your emergency brake pedal. Hope this works for you. Goodluck.
