Upon pushing the rear window sunshade button, sunshade will not go down. Stuck in up position. Could this be a fuse problem? If so, were would the fuse be located? Thanks

Check for power to the switch first. It may be a bad motor. I attached a wiring diagram of the system for you as well as the location of the fuse in the fuse block under the seat.
