Last night while the weather was bad my factory installed alarm was going off every 15 mins between 6pm and 645 am....needless to say my neighbors weren't too happy today. It was raining and windy but i've never had a problem with the alarm being sensitve at all. I can climb on the steps in the back and open the roof bin and pull on door handles without the alarm going off. I dont think rain would cause this problem. Any other ideas?? I was thinking maybe a short in the sensor or somewhere in the electrical system (i have been having the hatch light go on and off while driving). I have very limited knowledge of a cars electrical system but i plan on bringing the truck in
