How to fix cruise control on 2006 Cobalt

The most common problem is that the ribbon contact in the drum under the steering wheel has a defective circuit filiment. The part is referred to as the Clockspring contact.

Sounds like you might have an issue with either your multifunction switch or possibly your clock spring, if your cruse controls are steering wheel mounted.

sounds about right, probably is ignition switch, reason you don't get codes is because if power is'nt connecting to engine while problems occurs then ecm won't pick it up. you should have 2 ignition switches, (the lock cylinder and key switch, the other is the electrical, usually located under the dash, and commonly atttatched to the column close to the firewall, check connections first, it may just be a loose plug in connection

are you going uphill in overdrive gear . If the speed is lower than you set the crruise control might disengage. ?

Your best bet is to check what is happening by looking at cruise control data in the PCM and BCM. You will need a high end scan tool to do this. It could be as simple as a bad switch in the steering wheel or a brake switch that is bad or out of adjustment..

first ck fuse for cruise control,if ok ck power to main switch use a omp, amp meter for test, should have battery voltage to and from switch when in on position. if ok your next ck is steering wheel switch. air bag must be removed unhook battery wait five minutes remove airbag hook battery up ck steering wheel switch if ok below steering wheel is cable reel ck yellow connectors on both side for power if all have power to and from go under hood and ck power to cruise unit if ok pcm may not be letting it come on because of engine or trans readings dtcs pending or set can shut off cruise control

Must not have been much of a mechanic. If the engine runs and sounds fine sometimes and other times it doesn't then it does not sound like a mechanical problem with the engine. Sounds more like a issue with either the ignition system or fuel system.

Nope. Sorry to tell you there is no such thing as "just a fuse". Even if there IS a blown fuse involved, I can promise you that the fuse did not CAUSE the problem. Fuses do not cause electrical circuit problems - Electricl circuit problems cause blown fuses. This may sound trivial, but unless you can understand this simple "cause and effect", you will spin your wheels for days trying to figure out any electrical problems in your vehicle. Don't feel bad, probably 95% of the motoring public does not quite understand this....you are with the MAJORITY.

With all that said, you most likely have a broken contact assembly (also sometimes called "clockspring") in your steering column. This is the part that allows the electrical connections to be made at the steering wheel while at the same time, allowing the steering wheel to be turned around in circles. (See "A" in the diagram below.)

Here's the other bad news:
On most cars, the clockspring is available as a separate piece. However, according to the information I have available, the steering column on your VolksWagen is serviced only as a COMPLETE unit. Only the steering wheel, airbag module, and ignition lock cylinder can be transfered. So, you might be in for an expensive repair.

It could be something a simple as the cruise control switch(s)... or it could be the Cruise Control Module located in the engine compartment. There's also a 'clock spring' in the circuit between the steering wheel & the cruise module. Note: there are two sets of contacts in the brake lamp switch, one set for the brake lights, the other for cruise control. Properly diagnose the 'CAUSE' of the problem. Otherwise you could end up buying parts you don't need. Proper diagnosis is a 'hands-on' activity, which is nearly impossible to achieve here under the FixYa website
