I've got power locks and trunk release on my 84z. But the trrunk release doesn't work and my driver side door lock wont lock using the power lock button. Passenger works fine so I dont think the problem is a fuse, any ideas will help.

 

I really don't think it's a fuse. I would say your lock popper in your driver door needs lubed. Try that out and see what happens. As for your trunk, that may be a fuse, do you notice anythng else not working that should be? You may have a bad connection at the switch or at the latch, so check those out as well.
