hi all got in the car this morning and she started just fine, but with the engine running, I could hear the alarm module clicking and the alarm horn making a short low beep over and over. when I opened the driver door it would stop....close it again it would start the short low beep... after i turned off the engine and closed the door it was still doing the same.... after a couple of restarts and getting in and out of the car it stopped.... maybe the door pin? but why would it go off if the engine is running?

thks
