mine seems to work fine for months then one day it wont work at all i try both buttons several times no luck...then later taht samee day it will work again...

it also seems to drop like 3-5 mph when i set it and then it will speed back up to the speed i started at...i already adjusted it on the t/b....

 

There is a switch on the upper part of your brake pedal that cuts cruise off when you depress the pedal. Try adjusting that as far as the not working sometimes.

 

If the third brake light is out, cruise will not work......

 

it comes and goes...lights are fine....its a 6 speed and i checked the cluthc switch and adjusted it
