2013 386 peterbilt relay clicking

[suined]

I have a relay randomly clicking from what sounds like the steering column or below the speedometer. When it clicks repeatedly theres a squeaking noise coming from the radiator/ fan area. Could this be a relay for the fan? I talked to the previous owner and he had it at Peterbilt 2 times and they couldn't figure it out. I dont notice it causing any harm but I like to fix things that arent right
