Same here. I've uploaded the 318ti Electrical Troubleshooting Manual in case anyone wants to take a look.

Maybe the A/C condensation is affecting the alarm brain? Also, I think some of us added a mod to flash our hazards using the alarm remote. I believe this involved adding another relay in the hazard light chain, so that's another suspect.
Let's put our heads together and figure this out.
