disciplejohn52 Posted July 17, 2014 Share Posted July 17, 2014 93 legacy 2.2 I have a question about my almost functioning cruise control... On flat land doing 70, I'll set the cruise control. The speed will drop to around 55-60 and hold steady. If I go up a slight incline it'll drop. If I go down a slight incline it'll gently get back up to around 60. So it IS working, just not engaging the accelerator to hold the speed constant. I don't know enough about cruise controls to know where to start troubleshooting, so....HELP!

Gloyale Posted July 17, 2014 Share Posted July 17, 2014 Check the hose that goes between the Vac. pump and the Cable diaphragm. If it's leaking that would explain the slow loss of speed. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted July 18, 2014 Share Posted July 18, 2014 Leaking vacuum hose, leaking diaphragm on the cruise servo, or badly misadjusted cruise cable. Quote Link to comment Share on other sites More sharing options...
