Great blower fan wiring diagram - A wiring diagram is a simple visible illustration of the physical connections and bodily layout of an electrical system or circuit. It indicates how the electrical wires are interconnected and can also show where fixtures and components can be connected to the machine.

The blue /white is electricity out to the blower motor, if each strength wires in are warm and you've got a good ground then yes the relay is awful if the blue/orange wire isn't always warm.

With the ignition transfer within the run function, get right of entry to the blower motor relay and take a look at for power on the blue/white (bl/w) cord with the relay connected. The relay is located on the top driving force's facet of the tool panel with numerous other relays. If there may be no electricity at the bl/w cord, check the blue/orange (bl/o) cord that is warm-at-all-times power fed to the relay from the 30 amp blower circuit breaker in the instrument panel fuse box. Also test the blue (bl) wire of the relay connection for ignition-fed energy which is supplied via the 20 amp wiper fuse of the device panel fuse container. Test the black (bk) wire to verify it is a superb ground for the relay. If the bl/o cord and the bl wire each show power and the bk cord shows to be a terrific floor, it indicates that either the relay has a connection issue, or that the relay is defective. Disconnecting the relay and jumpering the bl/o cord to the bl/w wire ought to then result in a going for walks blower motor with full electricity to the blower motor connection. If there may be strength on the bl/w wire of the relay while it is plugged in however no electricity to the bl cord on the blower motor connection, provider the circuit for an open among the relay and the motor connection. Look into the circuit connectors for a likely corrosion/connection trouble and provider them as essential. The bl/w wire runs thru c242 that's a white 16-terminal connector positioned close to the grab pedal. It changes colors proper near the blower motor itself.

So if the blue orange is getting no electricity then want to replace it. I checked the relationship to the fan and with the putting of the fan pace on high it is analyzing three.4 volts.
