A few things to try:
Swap the relay for an equivalent known good one.
Check all your wiring. Use a multimeter.
Try powering the horn directly with wires that bypass the relay.

A good number of parasitic drains reported on this forum turned out to be either aftermarket alarm systems or the radio. As you said, it can be a challenge to pin down, but maybe those are some good places to start.

FOUND IT!!!!! it was the GPS, we just disconnected it and the problem was solved. Very annoying, took a lot of trial and error to find it.
Since the 2006 doesn't "natively" have a GPS, that must have been some sort of add-on, right?

Don't worry about it. We're all here to learn. I'm just glad you found it and fixed it.
