I would set it at 60 and it would hold speed great. 2 days ago my cruise stopped working like normal. Now I set it at 60 and it doesn't start to increase speed till 57 MPH but it doesn't build speed to 60 it stays at 57. Then I noticed it would gradually start losing more speed. The cruise switch is on and so is the dash light. I started setting my cruise at 63 hoping may be it would hold 60 and it does for a little while then gradually loses speed. Not sure what to do next.
Check the linkage at the advance to se if it is broken. Some are by mechanical connection and others are by vacuum. If vacuum you have developed a leak and must replace the controler to make it work again.

here are two switches that are the usual causes of the cruise kicking
out. they are both under the dash. One is the switch for the brake
lamps (stop light switch). the other is for the clutch if you have a
manual transmission.
if you follow the brake pedal up under the dash you'll find two
switches at the top of the pedal. (it may be one switch but I think its
two). the top one would be for the cruise control. if the switch is
loose it will cause the cruise control to think you're stepping on the
brake and that will disengage the cruise control
same with the clutch pedal if you have a manual transmission; if the
switch is loose it will indicate you are pushing the clutch pedal in
and cause the cruise to kick out
other than that you'll have to check all of the connectors. If it does
engage then the fuses and actuators should be good and it would be a
loose connector or switch that's kicking it out
also, i assume your speedometer works; if its not then that's your problem as the cruise won't engage under 30 mph
SOURCE: MY cruise control on my 03 trailblazer ls works intermittingly
short , loose connection or relay --most likely ---those little green light flicker or come on when generally there is an intermittent short, loose connection or a relay or fuse going to fail soon
and nothing works without a good ground ---one could check if the correct voltage is reaching the cruise contol system and go from there
Just my 2 cents --wiggle the connections --gently ---the cruise control is a complicated sysytem somewhat --you may need another symptom to appear to narrow this down more
but then again --I hate Tow trucks it's a GM --SELL IT Buy a foreign car don't go to ford either
a friend of mine once told me --a 30+yrGM master mechanic that thanks to GM's faulty wiring harnesses and stuff HE will NOT ever want for work and Ford isn't any better --
Get the Toyota if you can that is --unless you are a GM Fan
then sorry my bad no insult intended --

if the fuses are ok then i would say that there is a distruption between the cruise module vehicle speed sensor and the computer(ECM). unfortunately this is something only a qualified tech with diagnostic equipment can correct. i'm sure there are stored fault codes that the tech needs to check and reset. it's been my experience that oftyen times when this problem happens it has to do with the transmission control module which dictates how the engine and the transmission sync up to shift properly and your speed is measured through the transmission circuit thus the cruise control circuit is slaved to that.anymore questions feel free to contact me . just click my user tab on this site

Make sure the cable from the cruise control motor to throtle is not broken or unattached.
