There is a little silver looking box (circuit breaker) say an inch long by 5/16"" wide, in the fuse block. Actually there are a couple in my 88. My wife has a tendancy to kick the fuse box getting in and out, she has knocked the circuit breaker onto the floor more than a few times.
If the curcuit breaker is still there and the bayonet connectors (contact tabs) aren´t broken, it´s likely there is an open circuit at a connector someplace.
