Weird Problem W/ A Friend's Alarm System After Washing Under The Hood?

Question

We both washed our cars, cleaned the inside and then went and washed the motor and everything under the hood at the neighborhood self car wash. We used their engine degreaser and then cleaned it off like normal. Have done this several times. On his car (99 Civic EX 5 speed manual), he has an alarm system. Before the wash, you could press the button to lock it and it sounded loud and normal. Same thing when you unlocked it. Now, after the wash, he locked the car and unlocked it and it sounds extremely wimpy. Like if a dog was dying and he tried to bark his loudest. Doesn't sound as strong. I don't know if that'll hurt the alarm system by going out if it got wet, or what.

What would cause the wimpy sound after washing under the hood? And how to fix that? Just doesn't sound the same. Thanks

Answer 1

check the alarm siren may have gotten water in it make sure it point down ward and not up it usually a Little black horn looking gadget with a red and black wire leading up to it

Answer 2

yeah, It sounds just like the post above. Locate the alarm and loosen it up a bit so you can listen for any water sloshing around, because you may have flooded the inside where the speaker is. just drain it and re adjust it so if the engine compartment gets wet again, nothing will drip down inside
