Help With Electrical Issue
I'm hoping to get some help on tracing an issue keeping the power seats and power door locks from working in my 91. When I purchased the car both worked and I haven't done any electrical work other than a new battery. According to the FSM the circuit for both run through the power accy 30 amp circuit breaker. In looking at the breaker I found that it trips and resets over and over. I tried a new breaker, but had the same result.
The power door locks go through a 15 amp fuse after the breaker, which is ok. Only the seats and door locks run through the circuit breaker and there is a diode in line between the breaker and seats. could the diode be the cause of the problem? And if so how can I follow to where the harness that contains it would be located.

It turned out to be a dead short on wire that ran through the center console to the power seat switch. Must have had a nick in the wire that eventually moved a bit to cause the short.
