Alarm Went Off and Now Almost Nothing Works
I'm brand new to the site, so if this is posted somewhere it shouldn't be, I'd appreciate some guidance in where it should go. Anyway, here's my issue...
I have a 1998 Mercedes E320 that I came back to at the end of the work day and tried to use my key fob to open the doors. It didnít work, so I decided to use the key to manually unlock the door so I could head home. As soon as I did, the alarm went off, and continued to do so for the next few minutes. I finally disconnected the battery under the back seat to get it to stop. When Iíd connect the battery back up, there was the flashing red light on the door unlock button, which Iím assuming was re-arming the security system. If I opened the door, the alarm would go off again. Even though the alarm was going off, the car would start and I could even drive it, horn blaring the whole time.
I called the local MB dealer and they talked me through a reset procedure of locking and unlocking the front door with the key itself (not the fob), but that didnít seem to fix the problem. Finally, the blinking light went off and I was able to start the car and drive home without the alarm going off, and can at least drive it without the alarm going off.
The problem now is that there are multiple systems in the car that are no longer working. Hereís a list of what doesnít work anymore:
ē Power Windows
ē Windshield Wipers
ē Power Seats
ē Power Side Mirrors
ē Automatic Door Locks
ē Turn Signals
ē Automatic Trunk Unlock
What does work is the radio, the air conditioner, the lights (front lights and brake lights in the back)
Iíve done lots of reading online and canít seem to find a solution that will work. Iíve disconnected the battery for 30 minutes for a hard reset, with no results. Iíve checked all the fuses and everything looks fine. I thought it might be a rear SAM module issue, but Iím no expert. Iím fairly handy, so if thereís something to try, Iím up for it.
Any help would be greatly appreciated. Thanks.
