Theft Deterent problems
 

Ok, I have a 91 NA as a secondary vehicle, I let it sit a few weeks (I'm out of town a lot so I don't get to drive it much) and went to go start it today, and the horn started blowing. I know its not the button because it only does it when the key is turned on run. It does it whether the car is running or not. The lights also turn on during all of this. Does anyone have any idea where I should start? I've read that the alarm is under the glove box and I've already unplugged everything under there, same problem. Any help would be nice right now.
