1998 Nissan Altima Horn and Cruise Control Don't Work

The cruise control function gets power through the horn circuit on this vehicle. There is a 10 amp fuse in your fuse box located on the left side of the engine compartment. It is fuse #40 and like I said should be a 10 amp fuse. It is probably marked horn. This is more than likely your issue. Check the fuse and if blown replace it. This should bring both back.
