    Hi there i have a 2012 V left hand drive and the cruise stopped working. Does anyone know where exactly the fuse is? I do not see it under the hood or under the dash. Thanks Glenn.

    There’s not a dedicated fuse for cruise control.

    If the car has dynamic radar cruise control, you could check the ECU-IG NO. 2 fuse, which according to the Electrical Wiring Diagram (more info), supplies the driving support ECU assembly and millimeter wave radar sensor assembly; for the location, see the Owner’s Manual (PDF), page 416, item ㉑. Otherwise, cruise control is just part of the programming in the power management control ECU, and if any of its fuses (such as IGCT, IGCT NO. 2, and AM2) were blown, there would be warning lights, or the car wouldn’t be drivable at all.

    A more likely cause of inoperative cruise control would be a problem in the cruise control switch circuit, for which the Repair Manual has a step-by-step troubleshooting procedure. A broken wire in the spiral cable sub-assembly (also called the clockspring), for example, wouldn’t cause a diagnostic trouble code to be stored, but the cruise control button and lever wouldn’t work.
