2008 Avalanche LTZ 4WD Cruise Control Problems
#11
We have a 2007 Avalanche LT that has the same issue. We found this problem before we even bought it. We were told that it would be fixed. They replaced the brake switch and was told that it would fix it. It did not. Then they replaced the battery and said that there was a low voltage code that they thought the battery was causing the problem. So that did not work either. So I am now trying to find answers so that we can get it fixed without having to have it in and out for service over and over. Taking two carseats in and out of vehicles is not fun, over and over again.
Ours when you hit the button, the orangey yellow light will come on but it will not engage. You might try it once and it work, then a second later, it will not.
Anyone have any other suggestions?

Not bad for a half hours work for the dealer, but still cheaper than an extended warranty!

07 Avalanche intermittent Cruise Control
I had the same intermittent Cruise Control problem on my 07 Avalanche LTZ. It would work for a while, then just stop engaging. It would start working next time you started up the truck... for a while.
I saw postings in here that it was the brake switch. I tried trouble shooting it... when it was working, I just tapped side of brake pedal and sure enough it tripped it off. I bought a new brake switch rom Chev Dealer ($32.00) and changed it... pretty easy to do.
I noticed that the white grease from the original line installation seemed to be getting into the button on old switch... likely the root cause of the whole problem.
Thanks to others in here for all your help!

07/08 Avalanche Intermittent Cruise Control Problem
Hi, I had the same problem with my New Body Style '07 Avalanche. It's basically the same as the '08. It started out the same as others have said sometimes it came on, sometimes not. When I did get it working, it would randomly turn off and progressively got worse. One time, when it came on, I put my foot under the brake pedal and pull up/back toward me and the cruise control instantly went off. That clued me in to it being a brake switch problem. I tried fiddling with the wires and moving the brake peddle switch and occasionally would get it working again. So, I decided to look for a forum that covered this problem and that landed me here! I love the internet!!
I called the dealer for the part and learned that it is a #25981009 Brake Peddle Position Sensor. It cost me $18.00 plus tax, I used a small [3" long] flat tip screwdriver and it took all of five minutes to install! It is a rectangle switch that is located on the brake peddle arm. There is a small A/C vent that slides apart to give you access to it. Remove the wiring plug, use the flat tip screw driver to remove the clip and slide the switch along with the push rod that is attached to the brake peddle to the right and off of the brake peddle arm. Install the new switch in reverse and you are done! It's super simple!
Good Luck!

Check fuse
For the last 4-5K miles I have been experiencing intermittent problems with the cruise control on my Avalanche [now ~39K miles on it I know I should have taken it in immediately when problems started].
I've read most of the posts on cruise control problems and I don't have brake light or dash problems. The cruise light on the switch lights up no problem when the cruise is activated. However, when trying to engage the cruise nothing happens. Some times, if I'm lucky, and only after starting the truck it will work once. But cancel the cruise and then it won't work again.
Now most of the time the cruise will not work at all.
I have to say this really peaves me given I used to use it almost all the time driving to keep my mpg up.
Does anyone have any suggestions?
Thanks!!
