I think I've narrowed down my battery drain issue to be the power door lock system - either the lock relay or the ground wire to it from the actuator in the door.

Over night, my battery would drain down to 2 volts. And the power door locks magically stopped working as well - even with a fully charged battery. After recharging, I pulled fuse #8, and the battery was fine after 12 hours. I also noticed that when the fuse was in place, I could not manually unlock the 3 doors - the motor in each door was holding the locks down. I think this is due to the relay being continually engaged.

Assuming it's the relay, what is the best way to get at the relay? Remove the radio AND center vent? I've not been able to find any replacement relays via the usual suppliers. Any suggestions, or are they repairable?

Thanks.
