hi guys there seems to be a problem with the alarm of my '03 Iswara 1.3S. i took over from my father whom i think is a rough driver lol. about a month ago the alarm sound was slowly fading off whenever i activate it, and it's completely mute now for a couple of weeks. i thought it's not going to be a problem. just now when i activate it (unlock) to retrieve something from the car, it was ok. then problem came when i tried to lock it. the door locks pop back out as soon as it shut down. the next thing i saw was blinking of the turn signals without sound since it's mute now. the problem seems to be recurring and i had no idea but to lock the door manually.
what seems to be the problem?

i wonder what are the consequences of the muteness of the alarm sound if i prefer not to fix it as it seems to work properly (just without the sound)

tricky ones, it happened the first time on all doors, then only the right front and back door in the following times.

*but then when i made sure all the doors, hood and boot are closed properly, the popping out of the knob and the mute siren didn't happen anymore*

my trusty Saga is experiencing fans issue.
The aircond circulated hot air into the car. There were occasions when i stepped on the gas pedal, circling sound could be heard under the hood.
When i open the hood to inspect just now with the engine on, both the radiator fan and the other fan (aircond fan?) would stop spinning sometimes, and resume spinning after a while.
What seems to be the problems?
