Point me in the direction of what the error is in my car and I'd love to fix it, but even an experienced Chrysler tech has been left puzzled, I've searched high and low on the internet and all I fond is people including Chrysler techs throwing money at every component related to the alarm in the blind hope it will fix the problem. I don't have the cash for that.
What I have found is a glitch in the system, if it doesn't work on your car so what! Do you have the problem I have? I sure Mercedes didn't expect it to cause so many problems years down the road either.
The glitch in the system is in your car, understand that and we can go from there.
When you say siren box you mean the siren that is in front of the windshield hidden under the plastic cowl. You have changed the batteries in it and then replaced it.
Does the gas cap door lock when you lock the car using just the fob?
If not then the air line to it could be broken. It operates on its own air line. Could it be possible that the alarm light does not come on if this gas cap lock does not work properly?
Disconnecting the siren under the cowl does not have any effect on the alarm system, only the lights will flash if the alarm system is triggered.
