alarm questions

[Budfreak]

well, i went out last night and finally decided to tear the glove box out and check out why my alarm doesn't work. it was UNPLUGGED! after being a contortionist managed to plug it in and the led isn't working at all. i checked on it but it seems the connections are being made so i figure the led is dead. also, according to the owners manual, it won't auto lock the doors when you don't have a remote and it's supposed to honk the horn once when it arms. when mine arms i get no light flash or horn but my door locks unlock and then lock again and it's armed. it also says you have to lock it with the key but mine works by locking the doors and getting out like normal. it doesn't seem to work anything like in the manual. WTF? the shock sensor kinda sucks too. have to really hit the door hard to make the horn honk. oh yeah, it also says you'll hear clicking counting down when you get in. well mine flashes the lights and softly beeps the horn in a countdown pattern. it's so crazy! what does anyone know about this?

P.S. what's the little plastic white screw for on the module? adjust antenna or shock sensor?

P.S.S. this is the 6000th thread in tchnical q&a!!
