Well, fuddyduddy was right. It was a relay that was bad. As you face the firewall, it was the 3rd relay from the left under the fuse rail
. I think the coil went out.
Relay in position # 5 is the same type so I switched them out and the blower worked. I figured that it must be a relay as I was getting a good ground and when I put 12V directly to the fan, it blew.
I'll be down at the auto store tomorrow getting a new relay and then I should have air again.
Thanks to EVERYONE who offered ideas. I really appreciated it.
