I have a '90 Accord and my cruise control is acting up. When I push the switch on the wheel, the cruise light goes on quickly and then off. The cruise does not engage at this time.

It seems that if I wait for a while, it will come on after it "warms" up? I find it hard to figure out when it so so intermittent.

 

Check your cruise control vaccum tube.

 

How would I do that? Where does it start and end?
