Check under hood fuse box fuse ETC/ECM 15 Amp, check 10 Amp fuse marked Cruise in the instrument fuse box, and 15 amp Veh Stop fuse. There isn't a relay there is the set and control switch then the throttle body and powertrain control unit talk to each other, would need to trouble shoot using a wiring diagram. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
