Cruise control

[Mxdad303403]

anyone had issues with not being able to make the cruise work we have installed Lonny's switch set up but still no cruise does it have to have a third brake light and see a certain resistance to work on that light circuit

You will need to install a load resistor from the third brake light wire to ground.

Search for LED load resistor.

You must have a 2008 or newer or something. We were lucky enough not to have to use them, not that it's a big deal or anything. I just found it interesting.

Did you ever get your cruise control to work. I have a 2010 cobalt with the same switch panel and inop cruise control. I'd be interested in what you did. My third brake lamp isn't in use right now. Please advise
Thanks

I added the LED resistor and know the cruise functions. It has to see the resistance on the third brake light in order for the cruise to function

Do you remember which resistor you bought? Are you running a third brake lamp

Got it at Autozone don’t remember the name

Do you tap into and connect the positive on the light to ground?

Yes.

 

[jayrolls]

Yes.

Awesome Ty.

I installed the resistor on my 2007 and cruise is not working - should I be trying it without the resistor first?

Also, which way is on for cruise control - top of the switched depressed or bottom?

Maybe the older donors are different but Ion mine you turn the switch “on” to enable the cruise and then have 2 momentary switch’s for resume and set. Do you have a 2 position on/off switch or a 3 position switch?

Following. I installed the resistor and still don’t have cruise control.

Following. I installed the resistor and still don’t have cruise control.

Ditto. 2007 SS/SC Donor. Resister installed on third brake light. Clutch switches working, brake switch works. I sourced my own dash switches, but used the DF wire harness for them. Unless the DF supplied cruise switch has a special resistance or something, I doubt the switches are the problem.

Cruise has been low on my list of priorities, so I haven't really dug into it yet. Maybe someone has an answer and can save me the trouble.

Here's the resistors I bought: 10w, 100ohm. Not sure if they are the correct type or not.

The cruise controls buttons do have resistors in the wiring. I think they are included in the DF supplied button harness but they might be part of the buttons. I sourced it all without DF so I don’t know how they have it assembled.

If you wire in a third brake light that will also allow the cruise control to work

The resistors I’m talking about are separate from anything to do with the 3rd brake light.

I have the DF button panel - I am asking about the Cruise Control switch and not the momentary Resume or Set buttons. Since mine is not working, I am not sure which position on the 2-position cruise control switch is on vs. off.

 

[Sluggonaut]

So if I have a resistor wired into my 3rd brake light, I am affecting what is being accomplished by the resistors in my DF button panel?

My current plan is to pull the resistor and check it the next time I can get on the road.
