Ok....My cruise button doesn't work, even after I made it "stick" with a credit card corner. The cruise doesn't work, the ABS and the Trac Control lights are lit on the dash. Do I need to change out my wheel bearings?

 

Maybe. You could also have low brake fluid, or a broken wire to one of the hubs. Check the fronts first, they flex the most and are the most likely to break.

 

I have the exact same problem -- I have to keep my cruise "on" but the "set" button doesn't always work, and when it does, sometimes it kicks off and then these 3 lights come on that you listed.

 

Hi. I had the same problem this summer. In my case it turned out to be a bad ABS-sensor in the right front wheel hub assembly. I was lucky to find carpartswarehouse.com, where they cost only US-$ 68 per piece. Over here in Europe the OEM-GM-part cost EUR 470!
