Cruise stopped work today. Display says "Cruise Engaged" but it won't hold speed. I checked the two hoses for vacuum leaks but there aren't any. The big hose (connected to the brake I believe) doesn't have any vacuum pressure while engine idle, but I'm not sure how it supposed to be? The car is very clean overall.
There are no current/history codes related to the cruise control.
Any suggestions what to do would be highly appreciated. Thanks in advance!
