So it seems that everyone is of the opinion that 1.03 mA is no big deal. I will try to figure out where it’s coming from none the less. As far as why the horn began to blow on its own, I suspect that it was something in the steering column after all. Now that the steering column has been removed from the truck, the horn does not blow.
I’m assuming that 10.5 V would be enough to trigger the relay if there was a problem.
