Hi,
I've got a 1.6 N-reg Escort 'Mexico'. When the courtesy light is in the 'automatic' position (ie it goes on when the doors open and off when they close) the battery drains in about 24 hours.
I've not checked anything yet, like the door switches, but any suggestions.
The temporary solution is to switch the courtesy light off altogether.
Cheers,
Iain
PS It's not got a delayed-off courtesy light.
