Had the same problem with my 91.
You press the automatic locks and you get a little click from what sounds like the glove compartment.
For me it wasn't a fuse issue, and I don't believe it'* yours either.
It'* possible it'* a relay issue.... I find that with my 91 it'* worse in cold weather. But if you wait a minute or two then they will work. Odd I know.
Someone mentioned taking all the doors apart and greasing down the locks (and window motors while your at it) with white grease. I know it works great for the windows, and I heard that it'* solved some lock issues too.
Hope that info helps.
