brightz

So I'm not as mod savy as most and I was wondering if anyone has run into this. More often than not when i spawn in a vehicle with my trainer the horn just automatically starts going off and there is no way to turn it off. I've even tried blowing up the car and the horn still continues on. I was wondering if there is a fix for this or if its just a random glitch ill have to work around. It doesn't do it all the time just enough to make me have to restart the game a couple times which can get annoying. Thanks in advance.
