FRONT AND REARS FANS INOPPERATIVE

2007 Buick Terraza • 135,000 miles

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.

Use a test light or meter in underhood fuse/relay box check for power to Fuses # 27-28 key on

Check and test the blower motor run relay in the underhood fuse block and also could be coming from the body control module below left side of dash-

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.
