I have a 2005 Focus ZX-3 with 189,000 miles on it. I have two odd problems! Every time I apply the regular brake, my door ajar light comes on. The car is completely stock with no modifications. The only thing I've added is a trailer hitch and wiring. All doors are definitely shut properly. The wiring schematic Haynes Focus manual is a little hard to follow.
Another odd thing is that my trunk automatic deck latch stopped working. I replaced the latch itself, checked the relay, checked the fuse on the front of the fuse panel and checked the actuator switch on the instrument panel. All checked ok. It opens normally with the key, but just not with the push-button on the instrument panel. I don't have the auto-door lock system installed. But could it still be related to the fuse 63 on the back of the fuse box that I have been reading so much about? That one is a little hard to get to, so I wanted to ask a few questions first. One other thing, when I push the open button, I can hear the relay click, but no sound at all coming from the latch itself. Any suggestions?
