97 concourse deville windows will not open

The circuit breaker should be located in one of the electrical boxes - usually there's one box under the hood and one somewhere else, like under the rear seat or in the trunk. The tops of the fuse boxes should be labeled on the inside so you can find the breaker/fuse function and rating; if there is an identically rated breaker in the box you should be able to swap them to check whether that's your problem. Automotive breakers are usually self-resetting so there will likely be no 'reset' function.
