Basic Blower Fan Wiring Diagram Blower Fan Relay Wiring Collection | Wiring Diagrams - So if the blue orange is getting no power then need to replace it. I checked the relationship to the fan and with the setting of the fan velocity on high it is analyzing 3.4 volts. With the ignition transfer in the run function, get admission to the blower motor relay and take a look at for strength on the blue/white (bl/w) twine with the relay related. The relay is placed on the upper driving force's side of the device panel with numerous other relays. If there is no power at the bl/w wire, take a look at the blue/orange (bl/o) wire that is warm-at-all-times strength fed to the relay from the 30 amp blower circuit breaker in the device panel fuse field. Also check the blue (bl) wire of the relay connection for ignition-fed power that is furnished via the 20 amp wiper fuse of the instrument panel fuse field. Take a look at the black (bk) twine to verify it is a great ground for the relay. If the bl/o cord and the bl twine each display power and the bk twine suggests to be an excellent floor, it suggests that either the relay has a connection difficulty, or that the relay is faulty. Disconnecting the relay and jumpering the bl/o twine to the bl/w wire have to then result in a running blower motor with complete power to the blower motor connection. If there is power on the bl/w cord of the relay when it's miles plugged in however no power to the bl cord on the blower motor connection, carrier the circuit for an open between the relay and the motor connection. Look at the circuit connectors for a probable corrosion/connection difficulty and carrier them as essential. The bl/w wire runs via c242 that is a white 16-terminal connector positioned close to the snatch pedal. It modifications colours right close to the blower motor itself. A wiring diagram is a easy visible representation of the bodily connections and physical layout of an electrical device or circuit. It indicates how the electrical wires are interconnected and can also display in which fixtures and components can be connected to the gadget. The blue /white is power out to the blower motor, if both strength wires in are warm and you have a terrific floor then yes the relay is bad if the blue/orange twine isn't always warm.
