My alarm siren crackles and cuts out so I'm assuming the internal rechargeable batteries are failing... as someone else mentioned, it almost makes more sense to try and splice in an aftermarket alarm siren at this price.
The AA is the non beeping module when locking/unlocking the car, the AB beeps.
The difference in price is basically two times for the beeping one. The AA is now obsolete, a few may be around though. If you dig one up on eBay you may get one that is a few days from failing.
I am going to put new batteries in my old non beeper before they leak as explained by ala-xfire and maybe sell it.
Do not buy the part using the Chrysler part numbers, use the Mercedes part number as it will be cheaper by far.
