Hi. Both the front and reare fans have stopped working on my mini van. They stopped at the same time. I have checked the fuse indicated in the owners manual and all seems well.

Seems strange that both fans stop working simultaniously.

I checked fuses #26 & #27 (diagram on underhood fuse box lid) and there is no power to either side of the fuse.

When I run a wire from the battery + to one side of the fuse (#26 or #27) the fan opperates.
