Door Locks Chattering

The door locks keep chatting when i try and lock them. The relays are also chattering.and the battery will drain 2000 Cadillac Escalade 200,345 miles help me please.

Answer: Normally chattering relays and locks means a low voltage condition. Usually caused by a bad relay, but you say the battery is also going dead. If you have a non-factory alarm / locks / remote start system, have that removed or disabled first. If that does not fix the problem, then you are going to have to trace down a wiring shirt. On This truck it could be anywhere in the miles of wires in the dash or under the carpet.
