AC problem

[1989Art911]

I have a 1989 911 Carrera and have replaced the AC blower motor with a new one from Pelican Parts. Now the AC fuse (#2) in the fuse box gets extremely hot when running the AC. I have isolated the condenser fan and the compressor so I am sure the blower motor circuit is the source. Sometimes the heat is so high, the fuse distorts enough to lose contact. Anyone have a suggestion? It would be appreciated! Glad to be a part of the forum. P.S. The new fan works on all speeds and seems considerably more powerful than the original.
