Camaro Cold Case Electric Fan Relay Thermoswitch Sensor And Wiring Kit If you jump the wire to ground on the passenger side fan switch and the fan doesn't come on, you have a break in the wire some where in the harness. you could route a new wire from the sensor to the relay. the fan switch may be set to come on after 220* if the fan operates when the wire is grounded out. Typical fan wiring. the wire from 86 goes to the fan switch. in the diagram attached when the coolant reaches the set temp the switch closes and provides the ground path to the relay that closes the relay and the fans come on. when the temp drops the temp switch opens and the fans turn off.
Q A 86 Iroc Camaro Fuel Pump Relay Location Cooling Fan Relay The fan is controlled mechanically through an in cylinder head thermal switch and through the. mechanical a c slider switch. the in cylinder head thermal switch is designed to turn on the fan. when coolant temperatures reach 222°f (or higher) or when the a c is turned on. there is no. ecm control for the fan on single fan applications. objective. The ecm grounds the coolant fan circuit when the coolant temperature sensor indicates the temperature is greater than 222° or when the a c head pressure is greater than 232 psi and the vehicle speed is less than 35 or 40 mph (depending on application). when this circuit is grounded, the fan relay is energized and voltage is applied to the fan.
