Ok, so twice while driving in the past week my TC Off light has come on for no reason.
It almost 'blinks' on/off and I noticed that the light on the TC button blinked as well.

If I try pushing the button it has no effect, the TC lights continue to blink.
It only does it for like 10 seconds, and then it appears to go back to normal.

The first chance I get will be to inspect the WSS. I only need to check the fron two, right?

Any other ideas?

nope there are also 2 on the back wheels...check em all

TC compares the front wheels (which can slip) to the rear wheels (which can't lose traction when accellerating). The rear is the reference. This does sound like a WSS problem. Most intermittents are. Either something with the connector or foreign (US) material in the hub assembly itself (ice/snow).

Sounds like you are heading in the right direction. I would suggest unhooking and checking all connections for rust/corrosion. Then reassembling.

I had the hub replaced on my front rightside a few months ago.... I wonder if the front left side is going now too...... :?

Are you hearing noises or do you suspect the WSS is bad on the left?

Ok... I found the two sensors on the front wheels.

The connections seem ok, but what the clips plug into seems 'loose'.... both sides seem this way.
I used some cleaner spray in the connectors, but it didn't help, the TC light still flickers sometimes.

I was unable to find the ones for the rear wheels, could someone guide me to exactly where they are?

Raise and support the car.
Looking at the inside of the wheel, you will see the drum brakes. On the backing plate of the drum is an electrical connector and wire. Those would be them.

Should the front pieces feel.... loose.

Not the connections, but what the connector connects to...... if that makes any sense.

I have been having TC issues too. How would you know which WSS is faulty? I can hear the TC going when it shouldn't be...such as durring a normal turn around a corner (at an intersection). Sometimes my TC Off and ABS lights come on.
