had to go out to the car to try it. pushed and pushed at the back but couldn't get it off then slipped my key (for lack of a better lever here at work) sort of inbetween and under the front of the U to get it away from the anchor in the very front of the U piece (closest to front of car on top of fuse box blue plastic piece holds front of U down) yeah anyway popped the U off squeezed the back and I was in business. Thanks for the heads up, worked like a charm once I fured out how to release the front of the U. Hey if all else fails just use chopsticks to swap the fuses out!
