Cruise Control cancels when windows roll up?

[deangrell]

Got a weird one! I was driving down the road, cruise set at 70 and I heard a noise that I attributed to the wind blowing through a window that wasn't rolled up all the way. So I reached over and pulled both front window toggles up to ensure that the windows were not down. This cancelled my cruise control. I sped back up, reset CC, and pulled both buttons again...same thing. Can anyone else duplicate this? Any ideas?

I am guessing that you own a 07 - 09 truck... There is a PCM update for this. Go to the dealer and tell them about it and they should be able to reprogram with the new software update and get it all worked out. Tell them to reference Document ID: 2368552.

Appreciate it dm600, but dealer said GFY. That update is for 08 and up tahoe/yuks/suburbans and 07 up silvys/sierras. Anything else it could be?

 

[dm600]

Still not sure what year and model vehicle you have. What is the mileage?

Apologies, 07 Tahoe LS 4WD - 39k miles.
