Now and again, your temperature reduction fan stops employed because a sensor has gone bad, but the fan works just fine. A way to get around this state of affairs is to wire in an on and bump off switch. This switch works away eliminating the priming coat joining when it is switched "slay" and reconnecting the ground when it is "on". The process of wiring this switch is relatively easy. You just need to know the correct stairs.
Step 1
Locate a convenient pace to mount the switch. A good place is somewhere out of the way but lul inside reach. Clean that spot with rubbing alcohol and use the stunt man-sided tape that was included with the trade to hold IT in base. Use a screwdriver to screw in the ego-tapping screws that were included with the switch to permanently check it in place.
Gradation 2
Locate a 12-volt power beginning by using the multimeter. A good source close to the replacement is the cigarette lighter. Cut the power telegram up to the lighter, then cut off a half-inch of coating from either side of the cut.
Step 3
Cut a piece of wire that is foresighted enough to reach from the lighter to the switching and calm be hidden. Cut a 1/2" of coating from both ends of the wire, then seize a trot that was enclosed with the switch along one end of the wire and press IT into the 12-volt input yellow journalism of the tack.
Stride 4
Construction the two ends of the lighter wire and the strange remainder of the switch wire and solder them exploitation solder and a soldering iron. Tape the wires with electrical tape.
Step 5
Cut threesome pieces of wire long sufficient to reach from the switch through the firewall to the front of the locomotive engine compartment. Remove 1/2" of covering from each end of some wires.
Measure 6
Run the wires through the dashboard, hiding them as well as possible. Remove the rubber connect the firewall, then pass around the three wires through that hole and replace the rubber plug.
Step 7
Play ii wires to the fan motor. Cut the power and ground cables from the devotee motor. Remove 1/2" of covering from the positive and pessimistic wires functioning into the fan motor. Attach single of the untested wires to the positive wire and one to the damaging cable and solder them together. Protect them by covering them with electrical tape.
Step 8
Situate a consistency background below the hood of the vehicle. A obedient way to locate a footing is to follow the ground telegraph of the battery.
Step 9
Remove the ground from the physical structure using a ratchet and socket to loosen the nut. Connect the "eye" connector to the past remaining wire using the wire stripper to crimp the connector. Put the "center" connector ended the ground stud on top of the ground cable, and so tighten the nut down until it is secure.
Step 10
Attach the connectors that were included with the switch to the three left wires inwardly the vehicle, using the wire stripper to crimp them on.
Gradation 11
Male plug the connectors to the corresponding tabs on the switch. The torso ground connects to the ground input, the fan positive plugs into the 12-volt output and the winnow negative plugs into the ground output.
Tread 12
Test the sports fan aside turn the car along and verifying IT turns off and on as you change the transposition.
Secure the wires using ZIP ties. Pay special attention to avoiding moving parts and keeping your feet under the splashboard.
