The cruise control in my 99 Yukon does not work. The fuse is good and the brake light switch seems to be working fine with all lights good. Can anyone help figurenthis out before taking a trip in a few weeks. Thanks.

More than likely the brake switch itself is bad. Common problem. Weird thing is the brakelights will still work fine though.

I fixed it. It came up with a code for low voltage brake light switch. What a pain tp get to it to change, no room. It works fine now. The brake lights always worked fine.Thanks
