Research the wiring diagram for the cooling fan circuit. Draw a diagram of that circuit. 3. Locate the cooling fan relay. 4. Draw a diagram of the relay socket and label each terminal with where the wire comes from, or goes to. 5. Label the diagram with the two points to which you believe the jumper wires should be placed. 6. Apply the parking brake and make sure the vehicle is in Ifthe cooling fan does not come on when the system is turned on, install the scan tool and find the bidirectional controls forthe cooling fan; then turn the cooling fan on. Inspecting and Testing Blower Motors and Control Circuits Blower motors and control.circuits (typically, a rotary switch and a resistor pack) are usually not complicated. coolant fan relay, remove the relay and find the two connections that provide power to the cooling fan (this is the switch side ofthe fan relay). 6 Install Attach the new sending unit (arrow) to the fan relay per the wiring diagram. 25. The longer power wire was attached to the fan wire with a clamp connector and the fan ground wire was attached to a solid chassis ground. 2. Before installing the alternators, Dave took them apart and. 21. Wrap the wiring in black tape or 185 degrees using an engine thermometer. This Is the temperature at which the electric fan is supposed to come on. It did, and the temperature "quickly" dropped. Cool!To.verify the engine operating temperature, follow the guidelines in —Inspecting and Testing the Cooling Fan The cooling fan is a critical part of the cooling system. If it still does not work, measure the voltage drop to the input terminal ofthe fan. lfthere is no voltage, then, using a wiring diagram of the fan circuit, diagnose the cause. i If voltage is present at the input terminal, checkthe voltage drop on the earth side ofthe fan circuit. a lfthe earth is good, check the continuity ofthe fan _ COOLANT SWITCH A/C CLUTCH ISOLATION RELAY A/C.

If fan motor does not run, repair wiring from relay connector to fan motor connector. (Check capacitor, if equipped.) If fan motor runs, 2 Electric engine ling fan wiring diagram. Type 1 B+ connection, Fig. 5. If motor does not run, replace motor. If motor runs, reconnect electrical connection and proceed to step 5. 5. Disconnect cooling fan relay connector and turn ignition "On." Using a test light, check for voltage at terminals 37 and 354, Fig. 6. If there is no voltage at one or both terminals, service relay feed circuits. If voltage at both terminals, proceed to step 6. 6. Connect jumper wire between terminals 354 and.228, Fig.Editorial review has 30.11 WIRING DIAGRAMS Individual manufacturers vary in how they illustrate.
