Where is the fuse or relay for an 1988 Toyota Camry power door locks?
I believe it is under the dash on the left side – by your left foot. There are two round silver relays and a rectangular circuit breaker tucked way up toward the firewall, beyond the fuses. These are used by the power windows and power door locks. You will have to remove one plastic panel to access them. If the breaker is popped you can reset it by poking a paper clip in the hole in its surface.
