Had a squeaky front heater fan in my 86 westy, got to the point it would blow fuse rather than turn sometimes.  I went with the "Mullendore Port" repair, and I'm happy to report things are humming along just fine now.  I hope the PB Blaster smell fades soon though.

I really don't have a spare weekend to pull the dash so this "fix" is exactly what a young father needs.
