Do the 99 2.5l come with an alarm or is it an extra, my car locks with the remote, but sometimes when i get into my car my interior lights blink as if there is an alarm but there is no sound. every once in a while when i lock my car with the remote it will make a strange hum noise, sounding some what of a beep that is from a dieing battery or something. Any ideas?

 

factory alarm likely ...

 

what do you think the problem could possibly... i thought maybe the alarm horn/speaker is out... not sure though

 

the factory uses one of the two horns, locations vary by year ...

test lock the car by keyless with window down reach in and open the door from inside , that will cause the alarm to go off assuming it's the factory one

 

when i do that, this is when the lights on the inside blink as if there is an alarm... but no sounds

 

yup likely the alarm horn is bad (or the relay)...

 

and every once in a while there is a hum noise like its a dieing beep when i lock it. where is the relay located for the alarm

 

dunno Mine was ripped out after 2 days

 

hmmm is there any one on here who knows where the alarm relay is located on a 99 model... if worse comes to worse im just gonna rip it out and replace it with an aftermarket... pleas help

 

easist way is to set off alarm and feel around under the dash for it ...
also go under the car and look for the horns one is the car horn the other is alarm horn check it for 12 volts when the alarm is going off ... 12v no noise= bad horn ...
