I own a 2008 4wd 1500 Suburban. The cruise control will work fine when outside temps are above freezing. However, when trying to use while temps drop to below freezing it will not set all the time. It usually take close to an hour of drive time before the cruise control functions. Anyone have a solution for this type of dilema?

The Reply Bot won't help you.

Is it truly Cold Weather or just a random event?

My Cruise control started acting up on 2008 Suburban last spring. Turned out it was the Brake Switch behind the brake pedal. $25 from the Dealer, took me 5 minutes to review and find the switch, about 1 minutes to replace it.

Here's a video

When mine would act up, I could not get the Cruise Control to set. It would then work for a while intermittently, and turn off if I hit a big bump in the road.

Thanks for the info Bird. I live in Michigan and the temps have dipped to -10 most nights for nearly a month. I will check the switch behind the brake pedal as you have mentioned. My Suburban has 220,000 plus miles on it. I wouldn't doubt the switch has some wear and needs replaced. A $25 dollar fix would be a real low cost repair with respect to all the other maintenance cost. Heading out to take a look.

I will likely replace the sensor soon with the hopes it is the solution to fixing the cruise control problem. Along with the cruise control issue the left rear turn signal lamp will not work. When I use the turn signal lever to turn left, the turn indicator starts to blink at a normal rate. Then after three blinks it starts to blink as if I blew a bulb. I replaced the bulb and the symptom did not disappear. So, maybe the issue is related to the brake sensor. I hope so. The turn signal problem is irritating and I have not been able to track it down.

Great video of the fix for the cruise control. Not only explained how to R & R the sensor but the video was nice and clear. Plus, the music was a good fit too.

The turn signal could be related to the multi-function switch, those are notorious for going bad. This was the case with my 1997 Lumina with over 300k. I would have to hold the signal lever, and slightly pull on the lever to get brake lights.
