I’m on the road 1200 miles from home and cc isn’t working. Worked just fine on the way out but won’t activate. Owners manual does NOT show a cc fuse. Anybody know which one to check as I imagine it must be tied into another circuit. Pita driving that far with foot only. Thanks

 

From what I've been able to find, there are several possibilities to start with.

1. Check the brake light switch. Do the brake lights turn on when you step on the brake pedal? A bad brake light switch or even a burned out brake light lamp can cause the cruise control to not work.

2. Does the "cruise" or whatever light light up on the dash when you turn the cruise control on even if you haven't set the speed? On most cars a light lights up when the cruise control is turned on and then it changes color or another light lights up when the speed is actually set. If the dash light doesn't light up when the cruise is switched on, the problem could get be a bad switch on the steering wheel or wherever the cruise control power switch is located.

3. The cruise control is often tied in with the ABS or traction control systems, and a failure in any of those can cause the cruise control to stop working. You may need to check any ABS or traction control fuses. Do any warning lights light up on the dash?

 

I’ll check those tonight in the hotel lot. The cc light doesn’t come on now and no other warning lights.

 

Brakes are working, no bulbs out. Checked those other fuses, all good. God I hate new car bs electronics. I’m stopping by a Chevy dealer in the am to diagnose.

 

Oh well. Other possibilities are a failed cable between the control module and the throttle body. The dealer will probably connect the car to a diagnostic tool first to check for any electronic failures. With the dash light not lighting up when the CC is switched on, it could be a failed switch on the steering wheel. (You didn't spill coffee on it, did you?)

If everything checks out from the code reader, then it's on to a visual inspection of the system. Have you had any previous problems with the CC?

Let us know how it comes out.

 

No coffee and it’s always worked as normal. Hope they can get me in in the am or it’s wait till I get home. ☹️

 

Allegedly the exhaust vvt solenoid is the issue. They didn’t have one in stock so stop at auto zone tomorrow and cross fingers.

 

That seems like a weird thing to cause the cruise control to stop working, but what do I know. It's not like servicing the cruise control on my '78 Toro, that's for sure. Most problems with that unit can be fixed with bubble gum and rubber bands.

I checked my local Autozone, and they do show this part in stock. I hope you have the same luck where you are.

They show several other brands available, but none are in stock and have to be ordered. I didn't check other parts stores.

How easy is this thing to get at? Can you fix it in the parking lot of your hotel, or do you have to tear the engine half apart to get at it?

 

The ABS on my '03 does not work, but my cruise does.

 

It sits on the side at the front on passenger side. One bolt. I don’t see how this should dick up the cc either. The service invoice said the codes are for this even though no lights were on. Although I find it interesting that in the printout it says to change the part and retest it. Huh? Retest what? It should work right? If not, how is it any different than throwing random stuff at it to see if it works? Do they refund you it if it doesn’t work?

 

The cruise was one of the few things on my 97 that didn't give any problems. Everything else that failed offset that.

 

I've never heard of a shop that does this.

Good luck!

 

If you buy a part, no. If you bought a job to fix it, yes.

 

Not clear what you're talking about here. Does WHO refund you if WHAT doesn't work? If you go to an auto parts store, buy a part that you think will solve a problem, install it, and the problem is not solved, then the auto parts store MIGHT take the part back as a return and give you your money back if it's still in new condition. But it's up to YOU as the purchaser of the part to recognize that it is your responsibility to be sure that the part you're buying is really needed. The auto parts store hasn't diagnosed your problem, you have.

But if it's a repair shop that charges you for a part that it installs in an attempt to fix a problem and the problem is not fixed, which is something they should be able to determine by doing a test drive before they give the car back to you, then the repair shop should NOT charge you for the part. The shop should only charge for parts that were actually needed.
