NO
There should be power at the blower at all times , the Reg simply switches the blower to ground, so if you have no power at the fuse , you have no power at the blower ..
Check the connections at the fuse and look for hair-line cracks..if not , start chasing the feed wire to the fuse connectors........do you have the exterior fuse .. there was a change from the fuse box on later models..??
