i was making fun of them my friend i left the car with them for 8 hours
they told me we checked everything and found nothing
your car has no problem at all and to make me pay they reprogrammed car computer ( just to take money )

so please i need your help

 

i really appreciate your advice but i went today and checked jambs and no problem also were found

do u have any solution to disable that alarm?

( even when i closed the door with the key it also make the same sound
and when it happened i open and close it again and it returns again after less than 2 minutes )

 

I don't know if the alarm on the H3 is the same concept, but I had the same issue with my CLK. Afterwork I'd get home and I'd lock it up using the key fob then in the night the alarm would go off, lights flashing - never failed. I was sure someone was trying to steal it or the various CF parts. Turns out that the auxiliary alam battery (located in the siren housing) was past its prime and when it discharged it signaled the alarm.

Again, not sure if our H3s use the same basic concept (back up battery) but it may apply. I swapped out the battery and all is now good.

 

You must have an aftermarket alarm system... Locking the dr door with the key does NOT activate the FACTORY alarm system! You need to hit the lock button on the key fob to activate the factory alarm system, & key fob unlock to deactivate the factory alarm system!
I've seen numerous problems with aftermarket alarm systems, and I do not recommend installing any aftermarket alarm systems...

Probably a defective shock/motion sensor from an aftermarket install..

well lets see,you can change the bcm, or,put a switch in the horn wire!!!

the horn fuse is not for the alarm. the alarm is in the bcm. the horn use is the horn fuse. the horn relay gets grounded by the bcm or the horn buttons.

 

Your cargo door jam switch has gotten wet. water will get behind the rubber boot and keep shorting it out . remove and replace and seal boot with RTV. Been there done that.

 

dear friend i don't have factory alarm just the factory alarm
and ppl told me closing the car with key will deactivate it but it just keep beebing

 

i didn't go with the car into water but might the previous owner did
i already begin to believe it's the door switches that needs to be replaced

 

you are right no fuse for alarm

 

This seems like a troll.

He talks about having checked the door jam switches and then comes back saying he now thinks it's the switches. Talks about not wanting to disconnect the horn to get some quiet (a 5 second job) yet says he removed the battery etc etc

Does not appear he has checked any of the suggestions.

If he was serious he would have checked all the switches for moisture/damage/shorting and in the mean time disconnect the horn when parking the car to avoid noise.

Then one minute he says he has no alarm and then says he does.

Locking doors with key does not activate the alarm so there is no way that the car would be making any noise if locked with the key.

Troll I say
