Thank you, MB Doc! You could be right! The alarm siren maybe going bad. It goes off and on intermittently. One thing I've noticed when I tried the 'Panic' switch on my remote, the blinker lights were flashing but there is no sound coming from the alarm siren. I can also lock/secure the doors/trunk with the remote without any problem but when I opened a door (with the window down) there was no sound from the siren (sometimes), but once in a while it's sounding - like I said intermittently. This is probably the same reason why the alarm siren is going on/off while I was driving. The anti-theft system should be off when the key is in the ignition. I will definitely start with a new alarm siren and see if this will correct the problem I'm having.

You guys and all the MB Master Techs are definitely a saving grace to all of us out here!!!! Keep up the good work.
