It seems that when I engage the cruise control at any speed when I press the brake she will disengage for a moment the reengage like you hit resume, the only way to get her to stop reengaging is to shut it off???? Ideas

Check the vacuum side of the brake switch. It could be plugged up with something.
The brake switch kills the power to the electrical portion of the CC, but it also has a vacuum switch that "dumps" the vac. off of the servo connected to the carb linkage.

Thanks for the info, was kind of figuring the brake switch but I wanted some feed back before I took the time to stand on my head to replace it....LOL

Check to see if someone hasn't just plugged the hose going to the switch...it has happened. The switch may have been the source of a vac. leak, and was just plugged to "fix" it. You may need to trace the hose from the switch all the way up...ya never know...

Heres one for ya Joel, how about a cruise control that continually gains speed Shocked Set it at 60, few mins later its at 65 then if I wait long enough its at 70, any ideas?

Probably a transducer issue, Mark. The transducer is on the driver side fenderwell, and had the speedo cable(s) coming and going from it. Could be dirty on the inside, or the grease has hardened. That would mean replacement, or repair.

It may be a longshot, but the servo(vac. acuator) may have a (small)hole in it, also, or the regulator isn't regulating.Adams' Apple2007-02-18 16:05:33
