Viper, trunk alarm/switch

I had a Viper Remote start alarm installed on my truck a few years back after being broke in to twice. Everything has worked great and I haven't had any complaints until recently. When I set my alarm, it shows that my trunk is open. I though maybe the trunk switch went out but tonight I finally decided to trouble shoot it and the switch isn't the problem. I followed the wires through the inside of the car and cut them in half about two feet away from where they wire in to see if maybe I had a short somewhere along the route. I am still getting the problem so I know there isn't a short in the wire. When I touch the wires together, I can here a click (which I'm assuming is a relay mounted to the floor behind a panel) but it's not consistent. I can click it by touching the wires together over and over and sometimes it makes a good click and sometimes it sounds like it barely does. I'm thinking maybe the relay is going out and needs to be changed? The car can sit without the warning sometimes for hours and then all of a sudden set the trunk open alarm off. Also, would it be common for the passenger door sensor to be wired into this relay as well? I'm trying to research all I can tonight so I'll know what I'm getting myself in to tomorrow. Any help would be great.

This is what I have figured out so far. Here are the connections on the relay: "Bosch 12v 20/30 A" "0 332 209 150" 87 - ground/frame 30 - taps into a wire that goes into the door 85 - hot wire (with alarm not set) into the relay 86 - goes to the trunk sensor and then comes back and taps into the 87 ground/frame wire. I have no experience with these alarms so I'm really not sure how this affects the signals that the alarm brain receives. Is there anything that I can do to limit this test to the relay to find out if it is happening before or in the relay? I hate having to ask for help but after being robbed twice, I hate leaving my stuff unsecured. Thx

The 30/blue doesn't tap into the door. It goes underneath the carpet back towards the engine compartment. That was a poor observation, sorry. I got the relay on a 12v power supply and my dc meter right now. I'm assuming the way this works is that with the closed circuit, the 30/blue should send 12v back to the alarm brain? If that's the case, then I think I've found my problem because the relay doesn't send anything back. So to sum it up, what should the #30 on the relay be doing while in a closed circuit?
