Re: Non-Stop Horn!
I found and fixed the horn issue! Somehow, a mouse or small rodent managed to get into the main electrical box that houses the RCM(the lid was on tight, so I don't know how it would have gotten in there). The animal chewed a bunch of wires on RCM connector "E", which goes to the horn relay. I had to use a ton of electrical tape, as there was so much wire chewing. I took a look at the RCM, and it appears to be in decent shape, with no signs of solder burns.
Now, I need to find a pest deterrent for my car!
