Thanks for your help. Mike

Sounds like the siren has triggered. Have you LOCATED where the beeping is coming from (AFTER you removed the NEG battery cable)? Check the lower hatch cavity for water. If none, pull the wire for the siren under the cowl. You might have a leaked siren battery and it is activating. Come back when you locate the beeping, we can go from there.
