1991 LS-400 - The power windows and sun room stopped working all together. I was thinking its probably a fuse. Can anyone confirm and let me know where to check the fuse? Thanks.

Well, I fixed it. Found a breaker on the fuse panel under the driver's side dash. After searching high and low to purchase a new 30 amp breaker - and being unsuccessful - I popped the cover and discovered the breaker could be reset simply by bending the metal tab back until it clicked back into position, restoring the circuit.

Cheers!
