Question about 1992 Toyota Celica
The convertible top does not work. There is no power at the switch that controls the roof and no power at the hydraulic pump that powers the roof. I cannot find the electrical fuse for the pump to see if it just a blown fuse. I looked through my shop manual's wiring diagram and could not find it there either. Anyone know where the fuse for the power top is hidden (in plain sight?)
Have you made sure that the button switch, located in the truck, on the left upper side behind a small access door, is moved to the power system side rather than the MANUAL side. This button disconnects the elec system to raise and lower the top manually.

Drivers kick panel shows a convertible top fuse , #4 15amp fuse .now i see something in the schematics called TOP STACK , googled it and it refers to a convertible top , wierd , but anyway , it shows a top stack switch , a top stack main relay and a top stack fuse and a top stack relay . if you have the same manual , work with me , does your motor that powers the top have a blue/red and a blue/yellow wires to it , and the switch does it have a blue/red , a blue and a black wire ? do you see in your manual a top stack fuse r/b #3 ?
