Intermittant Trac Off light

2000 Gr AM SE with 2.4L 4 cylinder. 92,000 miles; all original parts.
Occassionally, for no aparent reason and in no aparent pattern the
Trac Off light will come on for about 1-2 days...sometimes less. The
car behaves as usual and everything else works. Then at whatever time
the car decides the light goes off. When off, the button for the
traction control works normally. When the light comes on and stays on
the button doesn't seem to turn it off or make any difference in the
car at all.
Is there a known problem with this item? My flasher on/off switch had
to be replaced under warranty but I haven't seen anything about this
switch. The two switches are next to each other on the dash and look
the same if that matters...
Any thoughts? Thanks in advance.

I've got a '97 with a 3.1 V6, and it's called ETS in that year, and here's what the manual says:
Enhanced Traction System Warning Light (If Equipped) ETS If it stays on, or comes on when you¹re driving, there may be a problem with your Enhanced Traction System and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. The Enhanced Traction System warning light may come on for the following reasons: If you turn the system off by pressing the button on the shift lever, the warning light will come on and stay on. To turn the system back on, press the button again. The warning light should go off. (See ³Enhanced Traction System² in the Index for more information.) The warning light will come on when you set your parking brake with the engine running, and it will stay on if your parking brake doesn¹t release fully. If the system is turned on and the warning light stays on after your parking brake is fully released, it means there¹s a problem with the system. If the Enhanced Traction System warning light comes on and stays on for an extended period of time when the system is turned on and the parking brake is fully released, your vehicle needs service. 2-62

It could be a bad ABS wheel sensor. The front bearings have the wheel sensor built-in, and the ABS/ETS are all intertwined. I've seen bearings be perfect and the wheel sensor fail. ANd IIRC, Grand Ams, like the Malibu and Alero, are a little hard on wheel bearings.
