View Full Version : 06 DTS Cruise control with AC on

When AC is running and I have the cruise control on, going down hill the car picks up speed. But without the AC on the car maintains the correct speed. Any Clues?

Lack of power availability? Probably the same reason my '96 Stratus creeps forward slighty if your foot is on the brake and the AC is suddenly turned on. I noticed the Caddy does not maintain speed going down a hill. The Stratus downshits and revs like crazy just to keep your set speed.

I got a ticket the first day I ever owned a DTS for this very reason. I had the cruise set a couple miles over the speed limit. I set it and forgot about it. Going down a lengthy, but not very steep, hill I got picked up for going 10 over the limit. I try to watch it now!
