2004 Silverado 2500hd with manual transmission. I checked the fuse and it is good. Any ideas what else I can check before I take it to the shop?

The switch its self

Make sure there isn't more than one fuse ... ;)

not sure if chevys are all electronic or not. check under the hood for a loose vacum line or one that is split. also look for burned wires or a connector that has come off. you can also do a google search which may provide some direction. there are numerous chevy sites where members post problems just like that

That's truck is drive by wire so there's NO mechanical attachment..it's all computer controlled.

I would check the wheel speed sensors on the front hubs.
I have a 2003 and the the cruise control went out along with the ABS. I was told there are wheel speed sensors that are for the cruise and the ABS on the front hubs.
I know its not the brightest thing I've ever done, but I pulled the square fuse for the ABS and the cruise works now. Two lights on the dash are always lit (ABS and brakes) and the truck beeps for like 10 or 15 seconds when I start her. A check brake system message appears on the dirver info thing also.
I have driven vehicles for years that never had ABS and they stopped just fine. This truck will do the same if you just pull the ABS fuse.

Does the indicator light come on?

Tail light fuse (25 amp) under the hood is connected to the cruise control. Check that fuse.

Thanks for the input. The cruise worked as advertised yesterday. My guess is either a vacuum leak, or an intermittent electrical problem made worse with the heat this summer caused the cruise to fail on Sunday.
I’m getting a set of shop manuals from a guy at work so I can read up on this. Intermittent problems are a pain in the neck. You always know the problem will come back, just don’t know when. Thanks again.

There is no vacuum.
The likely issue is the speed sensor circuit, or simply the cruise control button is not working properly.

Is your check engine light on? Not sure about Chevy, but my wife's Subaru disables the cruise control if the computer detects a fault code. In her case it was a bad O2 sensor

My Envoy does the same thing.The cruise won't work for a while and then all is well.Apparently this is a common deal with GM.I just live with it.

Ohh..stick shift. There's a sensor on the CLUTCH which disengages the cruise! They stick or get out of adjustment.

Likely the clutch switch. Next time pull up on the clutch or kick the area where the switch is mounted and hits the pedal.
The dealer should be able to look at the PID to show reason for cruise disable.

Just had mine fixed on an 07 yukon. Mine was the brake switch under the pedal. Sometimes it worked and sometimes it didnt till it eventually gave out.

Had the same problem, on an old motorhome, the switch above the brake pedel was stuck open (or closed, forgot which), lubricated the switch, no more problem.

Thanks for all the input. After screwing up once in late July, my cruise control worked fine until this morning. It just wouldn’t engage.
Make a long story short, I kicked the side of the brake pedal and now it works fine. When I get around to really fixing the problem, I’ll go straight to the brake pedal switch.

yea might be a switch. probably thinks you are stepping on the brakes
09-23-2012, 06:53 PM
It's probably just the bracket/mount that the switch is part of. If I remember right it's plastic and prone to not staying in place...
