The ignition switch may fail causing a no start condition. This is not generally a theft system (passlock) issue because the security light does not illuminate or flash.
Vehicles with V6 engines may see the 30amp high speed cooling fan fuse may blow due to high start up loads associated with the high speed cooling fan motor. Our technicians tell us the high speed cooling fan wiring and fuse should be upgraded to a 40amp circuit to correct this concern. The fan wiring MUST be upgraded along with the fuse to handle the increased current flow.
