Sunfire alarm sounding for no reason
Focusing on switches: Start with the door switches. Pull the fuse for the dome lights. Reset the alarm. Does it sound off? The alarm feeds off the dome light fuse. Driver door is first: Often they wear out first and give us grief like this. Unscrew and disconnect the switch first. Replace the fuse. Carefully close the door so you don't loose the wire in the frame(attach a string to it so you can fish it back out if it falls in). Reset the alarm. Does it sound off or not? If it does, it is other than the switch or the passenger door switch (if a 2 door or 2 other passenger switches if a 4 door). Repeat process until the switch is found or all are eliminated. Switches are cheap, so replacing them will not break the bank. Disconnect the fuse again, unscrew the bad switch. Unplug it. Plug in the new. Screw it back in place. Reconnect the fuse and try it again. Repeat as needed until you have either found it or just limited your search area. Most often you will stumble upon it- chaffed wires, look plugs, bad switches). Yes, there is more, but I see this as the usual suspect. If you go back into the alarm, disconnect the alarm first, then observe the dome lights with the fuse in. It just may be a faulty control in the alarm, which is out of my territory. Let us know what you find, but start with the smallest things first. Good Luck!
