ok here is the wiring to give you an idea on what is involved when it comes to the low relay and its not much simply a relay wish you all ready replace , the fuses wish are good and that leaves the wire with the signal to the relay and pcm computer we already know there is power to the relay because if it did not get power the hi fan would not work so that leaves us with the computer or the signal wire.
