`05 LS w/25K miles. Wife's car. She never uses the cc, but I do whenever I drive it (trips). It doesn't want to engage. I worked the last time I drove it a few weeks back. The dash light goes on & off with the cruise button, but it won't set. I checked the owners manual for location of a fuse, but don't see one listed.

Anyone have any suggestions of what to check, before I take it to the dealer?

Thanks,
Rick

 

OK...here's what was causing the cruise control to not work. Both brake light bulbs were burnt out, causing the circuit to fault open. A coworker of my wife told her a couple days ago that her brake lights weren't working...she forgot to tell me. The dealer replaced the bulbs. The cruise control now works.
