Yes, it has a fuse and a relay.
I believe there is no fuse just for the cruise control. The cruise control circuit is covered by the PCM. However, I would check the switches on the brake pedal.
With your finger.
not 100% sure on 99 model, but on 92-97 accord it is under the dash, above silver cruise control module. gray with reddish base. It is called the main-relay since it runs both fuel pump and ECU.

Yes, a 1999 Dodge Ram Pickup does have a fuse for the cruise control. It is a "MIN10" style fuse - a small, flat, two-blade, red-colored fuse.
The PCM has nothing to do with the horn. The cruise and horn are probably caused by a bad clockspring, (not a diy part). The fan is usually a failed relay, which is located under the right front headlight, under the bumper.
All functions of the engine. Cruise, Alternator, transmission torque converter clutch,
I am having similar symptoms with my 99 Buick Regal. The blower motor will run all the time even with the keys out. When the blower isn't working neither will the cruise control. I have researched it and believe it to be the ignition switch. I have not replaced it yet, but feel that is the most logical thing. It's also possible that in your situation it may be either the Blower Control Module or a relay. However, it's likely the ignition.
If you mean the Constant Control Relay Module, it is located under the air filter.
Check your owners manual or the underside of the fuse panel lid. One fuse will be labeled for gauges and meters (possibly along with the cruise control, airbag and other systems). That's a place to start. BUT, if all of your meters are working and only the clock has gone dark I'd suspect the instrument rather than the fuse. Cheers
The headlight relay is integrated into the LCM (Lighting Control Module) located under the dash on the fire wall just above the transmission tunnel.
