Weird Electrical Issue

Strange electrical issue

Battery light comes on,  I here a click by dash, and blower fan quits.

The problem was intermittentant but now Blower fan doesn't work and battery light stays on.

Checked the battery voltage and alternator both are good.

Checked the ground from engine to firewall, its good.

Ran a test wire from battery to firewall to make sure its not a ground problem from engine to firewall.
