So I have had a problem with my factory cruise control. I've checked all the lights, connections, steering wheel switches, and pedal switches. There is something on the transmission maybe I haven't checked (variable speed sensor)? My question is can I take it to the dealer and get an "estimate" on what's wrong and the cost then just fix it myself? When they scan it will it be able to tell me what's wrong? Any info is appreciated.

Good luck on free diag scan at dealership. You might be able to get a free guess and a bid for replacing your BCM. A better bet is to locate someone near you with a Tech-II. Post the city you live in or near and go from there.
As to where to look.....verify all 3 of your center (high) break lights are working and your fuses on the BCM are good.....
& look at the 2A ?? Fuse #19 (Electric Power Steering, Steering Wheel Control). I could be off on that fuse.
If you search here, Coby7 has posted the diagrams on the 06 cruise control

Enjoy

Let me clarify that, I was planning on paying for the diagnostic scan. I'm just curious if I take it in and pay to have it scanbed then worker tells me it's this and this broke and will cost this much. Then I can just fox it myself.
Are you meaning find someone with a tech 2 on here?

Why don't you tell us the exact problem you have with cruise? And that's ( Vehicle speed sensor) and if it was bad your speedometer wouldn't work properly.

My cruise just doesn't engage in my 2006 cobalt with manual transmission . It worked fine then it started cutting out when I hit bumps and now it just doesn't engage at all. My speedometer works fine, all tailights are good, fuses that relate to cruise in the book are good, I tried testing the switches on the steering wheel and replaced with used switches, I took the pedal switches off and tested them and they work. So I'm lost as to what to do next?

You could try re-seating the connectors on the BCM. You may have a bit of corrosion. It happens with these. I believe pin 62 is cruise.

Do you suggest some electric grease on the connectors? The BCM is under the concave plastic under the hood right?
I will definitely try this, thanks for the suggestion!

BCM is on the passenger side of the console under the panel with the fuse logo. A bit of dielectric grease won't hurt.

So reset my BCM connector and the cruise worked a couple of times. It's back to working intermittently. While driving I pulled the set switch (right side) out of the steering wheel and I can move it around and get it to work again after it shuts off. Seems I may have a short in the wire for that switch? How is it routed through the wheel and down the column so I can chase it and look?
