Cruise Control Fuse

Hello, could anyone tell me which is the Cruise Control fuse or fuses? I've tried looking in the owners manual on pages 386-387 in the fuse section, could not find. My CC works half the time, and goes out. I would like to replace the fuse before I spend the time replacing the CC assembly. Thanks guys.

A bad fuse won't work 'sometimes'. It's either working or not.

Spiral cable under the steering wheel (literally) is a much more likely suspect. Especially if the horn is intermittent as well as the CC.

 

Yeah, I have thought of that. The horn seems to work just fine and I had the spiral cable replaced under recall back in 2013.

 

Even still... It is the most likely culprit. Spiral Cable.

 

Yes, my truck had this issue and I replaced the spiral cable (clock spring) and it fixed the problem. Just beware a good oem one is pricy. $300ish or so. If you had the recal done back in 2013 see if there is any extended warranty and if they can fix it for you. If not your out of luck. My horn worked fine but my cc would only turn on intermittently.

 

is it standard or auto?

 

Good point.

OP if it is a manual transmission there is a switch on the clutch that will kick off the CC. And for either the brake switch will do the same.

 

...or a bad ground somewhere.

 

It's an auto.

Well crap, yeah I hooked up a cheapo scan tool and it showed nothing. Do you guys think it could be the Cruise Control Switch Assembly?

My cruise control did that for awhile before stopping working completely.

While idling turn your wheel all the way to the left and try cruise control, then all the way to the right and try again. Bet it works better in one or both of those conditions because the spiral cable is failing.

 

This is going to sound out there, and even now it is out there to me, but definitely on one of my "top 10 strangest things I've seen in automotive." Fuses do sometimes not work, but are whole, and a simple matter of pulling it then reinstalling it restores functionality to the circuit again barring that the fuse is physically not blown. I have noticed it to be something that affects micro fuse equipped fuse boxes like the ones we have. It has definitely happened on my own truck before.

So to say they won't work sometimes and that it either works or not is simply not true. At least not true in all the years of my experience.

 

I think you are mistaken either a fuse is blown or it is not blown. If it is, blown it will not conduct current. If it is NOT blown, it will conduct current . This is not a sometimes thing.

That being said if it is not blown and not plugged in correctly then that could explain why you thought what you did. And when you unplugged it and re-plugged it back correctly it fixed the problem of not being plugged in all the way.

 

It "could be", but I would be looking at the brake switch or the spiral cable... But I suppose the switch is cheaper to replace than the spiral cable.

 

Devil's advocate here,
**what if** there is some corrosion or oxidation on the leads, and by pulling and re-installing you are making a new contact.
Food for thought.

 

Another possibilty...

 

Awe common, show some imagination. While a fuse is either blown or not, mechanical contact failure is not unknown so why not at least check all the inexpensive possiblities before forking over a roll. I'm not saying how likely it is but it hurts nothing to see. Also, I read in another post how improperly plugging in the spiral cable resulted in a bent pin and malfunctioning CC so try an RI of the cable checking the connector for obvious problems, could be a bad crimp on one of the wires or the tech just didn't push the connector all the way in. CC isnt a critical system so you have the time to get forensic. In the mean time start saving up for the more likely eventuality.

 

A lot of possibilities here really. Sometimes things aren't so cut and dry.

 

Possible bad brake light switch as well

 

Alright, so I agree with all above conversations. If I knew where that fuse was for the CC, I would replace with a new one. Can anyone tell me where it's at? Bad Brake Light switch? I don't know what that is, my brake lights seem to be working fine to me. Anyone want to tell me what to check for this?

 

As mentioned above it has been going in and out, I was able to use it on the highway after 30-40 mins of driving. Damn thing wouldn't turn off, had to slam on the brakes. Kinda makes me think it's the CC switch assembly that's messed up.
