First, Please review these articles:
Where's The Fuse?
What Else Could Be Wrong?
Then to answer the question you asked...
There are actually three
fuses involved in your cruise control system.
> The first is the "Cruise Control, EAT ECU" fuse. it is Fuse #4
in the Underdash Fuse And Relay Box. it is a 7.5 Amp fuse. This fuse also powers the gauge assembly, the alternator control circuit, the Radiator Fan Control Module, the Intake Air Bypass Control Solenoid Valve, The EGR Control Solenoid Valve, The EVAP Canister Bypass Solenoid Valve, the EVAP Canister Vent Control Solenoid and the Heated Oxygen Sensor Heater circuits. If this fuse is blown, the engine will not idle, The alternator will not charge the battery and the transmission will not shift properly. In general, a whole bunch of stuff will not be working.
> Next is the "Backup, Metering Lights, Turn Signals" fuse. It is Fuse #1
in the Underdash Fuse And Relay Box. It is a 10 Amp fuse. As you can tell by the description, your backup lights, dash warning lights and turn signals will also not be working if this fuse is blown.
> Last there is the "Stop Light, Horn" fuse. It is Fuse #30
in the Underhood Fuse And Relay Box located at the right rear of the engine compartment. It is a 20 Amp fuse. As you might guess, your horn and stop lamps will also not be working if this fuse is blown.
