On my 2007 Buick Van Terraza VIN: 5GADV33187D140777 my Cruise Control will stop working after driving a while. If I stop and restart the Van it will work for a while again. Thanks for any help, Howard

Those Terrazas share some tech with the Chevy Uplanders which led me to this forum post by someone after a Google search for ‘2007 Buick Terraza Van intermittent cruise’.
Check the post by ‘in2pro’ as it references a technical bulletin a dealer would use to diagnose an issue with cruise. In short, you can try a couple things:
1. Try the break pedal position with your foot in an ‘up’ position ( may be a pain in the butt to do ). Possible it will prevent the break switch from disengaging cruise.
2. Check your stop lamp assemblies. Remove the bulbs, clean the sockets and bulb bases, put them back in. This is a bit easier to check and doesn’t require a trip to a mechanic.

Do not know if this is relivant , but I drive a 2008 Silverado company truck .
It had a simular problem . Initially I could raise the brake pedal up with my toe & the cruse would work again .
Eventually replaces the brake light switch ( as has been suggested ) . This cured the problem .
