[Olive Oil]

Yes, I'm a newbie. And of course the reason I joined is because unlike other people, I have to try to figure out the vehicle problems on my own. With little to no money and being a single parent, I have had to take "Be a mechanic yourself" 101. Any instruction I can get on this course will be highly appreciated. This is my first Chevy as well as my first truck( this is what I call it)lol.

Thanks in advance.:tiphat:woohoo:

Cruise Control

I can't figure out why my cruise control stopped working.

 

[the roadie]

There are about 20 things that can suppress the cruise control function, most of them error codes that also illuminate the "Service Engine Soon" light, but not always. Is your SES light on? You may have to take it to the dealer, who has the tech tool that can talk to the PCM (engine computer) and ask it why the cruise isn't working.

Any other maintenance history, or work done to the vehicle, or any other strange things you've noticed when the CC stopped working?

 

[Olive Oil]

Thank you for answering

The SES light is NOT on. I thought it might me a fuse, but come to find out that there is no fuse for the cruise control itself.

:tiphat welcome to the site there are tons of info on the site to help you with your troubles

 

[the roadie]

Yes, in the good old days, a cruise control was a separate electric or vacuum powered actuator that pulled on a chain and yanked the throttle cable just as your foot did.

Nowadays, it's all drive-by-wire electronic control, and the accel pedal isn't directly connected to anything but two sensors. And cruise control is a software function.

You may need to get a diagnostic visit at the dealer or a decent independent mechanic with a good scan tool that can ask the PCM why cruise has been suppressed. The data is retained especially for cases like yours.

Thank you. I was hoping I could fix it. Guess that isn't going to happen. Don't know how I'm going to make that happen, but thanks for the advice.

:tiphatWelcome to the site,it may not be as expensive as you may think, maybe a decent dealer will give you a break?:hopeless

 

[Olive Oil]

Hopefully not. Unfortunately dealers usually need your car for awhile and I have no replacement. Maybe he can scoot me in Wed. afternoon.:thx

Hi Olive, before running to the dealer, let's see what we can do

There are a number of fuses involved with this system, some may be used for other things, but let's list them.
Fuses under the hood:
#22, #12

Fuses in the rear seat panel:
#39, #34

As someone said, in an earlier post (and as you know), operating the brake turns the cruise off. Check the brake lights, to see if they are operating as they should (a quick switch test).

The other problem area, is the multi-function switch (the stick on the column). There are 3 contacts in this switch, one could be bad; or a piece of the switch could be broken. Do the slides and push button seem to work normally?

Check those, and let us know.

BTW, welcome to the site. :thumbsup:

 

[Olive Oil]

I will check those fuses if I haven't already. The entire switch seems to be in working order as far as I know. I won't be able to check it tonight as it is rather dark outside. But first chance I get tomorrow, I will. I should be out here around the same time to let you know either way. Thanks once again.:woot:

HE is stating what HE has, he also said welcome!

 

[Olive Oil]

Ok, thanks for explaining it to me.

welcome Ms. Oil? :tiphat

Hope you figure out whats going on with that cc. The guys around here are very knowledgeable so don't get too discouraged with the truck.
Do you have the Chiltons manual for the truck? That was probably my best investment so far.

 

[Olive Oil]

I just got this truck not too long ago. It has been great running so far. And it has a limited two year warranty. I looked in the recall section and it said something about a powertrain, so I dunno. I will have to get this fixed because I live about an hour away from my job, and the cruise control saves me from getting speeding tickets. ( If ya know what I mean).:nono:

 

[Kman1022]

I'm with ya, I drive 94 miles each way to work and cc saves me plenty of tickets.
