cruise control issue, it doesnt work... Options

1999 celica gt liftback manual.

so im cruising along the other day, and just for fun, i decided to use my cruise control. i turned it on, and nothing. the light didnt turn on. i tried it at a whole bunch of different speeds and gears and still nothing. i read the owners manual and it says that if the light starts blinking and then stops lighting all together that its busted. well it never did that. it just stopped working. common issue? Could it have something to do with my disconnecting the battery recently? (i was lubing the alternator bearings). To be honest this isnt a major problem, who uses cruise anyway? its just irritating because ive had this car for less than a month. anyway, some input would be awesome
