To answer a few questions.....
I believe there is one fuse in there somewhere that controls the Cruise system??? Check the fuse....
For you 82 - 83 owners who still have the 85mph speedometer.... If you keep insisting on pegging the speedo at 85 mph, this is a GREAT way to kill the speedometer sensor that is behind the instrument cluster. If you kill the speedo sensor, then your cruise stops working, because it can't get a signal from the speedo sensor... Solution..... A. Don't plan on going faster than 84 mph (not 85) for any length of time. B. Switch over to the 130 mph speedo cluster.... No more broken speedo sensor, because of a pegged needle. :shock: :shocked!: :shock:
Cruise speed memory..... Unless you're one of those that does not have a owners manual..... The owners manual DOES clearly state that if the speedo drops below 25mph, the cruise system does drop memory & you will have to reset it.... This is a safety feature, something that I wish GM vehicles had, but don't.... Example.... 11 years ago, I was in Florida on vacation & a bunch of us rented a Chev Illumina Van.... Was leaving a toll booth & from a 5mph roll, I decided to test out this theory that the GM's retain speed memory, so I pressed "Resume"..... From a 5mph roll, the cruise engaged, the gas pedal went to the floor, downshifted to 1st & proceeded to accelerate to 65 mph.... 3 seconds later at 30 mph, I tapped the brake pedal & was glad that nobody was driving slow in front of me....
So yes, this IS a safety feature & there is a reason why the Toyota cruise works like this.
