latest update....

-blower motor removed....lots of dust from brushes, and armature really worn down...I grounded blue wire to fan motor body and still no fan. If I supply power to fan directly from the battery it works. Given the condition of the armature I might change it out any way.

-I had the new fan installed and thought before I had it all together I would test it. I made sure all connections were made and turned on economy setting setting and fan on high...still no fan. While I was trouble shooting I heard a relay clinking in the fuse box area closest to the firewall.

-Im afraid to change blower regulator if the relay is bad there is too much money involved

Please help!
