Alarms are a biotch. They are tied into all kinds of crap. You might have a problem getting that out of there.Radio is after market, alarm I think is after market and wasn't working right when I bought the van so that's another one I'm going to look at. Actually I think I'm going to just take the alarm out regardless. Before I bought it it was a Comcast van, they had a lot of stuff installed which was removed before they got rid of it. So could be something from that too. I didn't think about checking at the fuse box, that should narrow a lot down quick.
