It goes direct from the brown/tan wire going into the resistor pack to the fan. As it did work on high it might be a problem with the contacts on the connector not making good contact.
Ok so I ended up going to Radioshack and buying a thermal protector fuse for $1.50. I thought it would be worth a try before shelling out another $50 for a new blower resistor pack. I carefully cut out the old fuse and soldered in the new fuse, plugged it in and screwed the pack back into place...
here is a link with pics that describes that process: http://www.geocities.com/chmwatson/F...elink_fix.html
It works except for the high setting. I think that's probably a switch contact problem on high.
I never should have tested it while it was dangling outside of where it screws in. The lack of a fan blowing on it cause it to heat up and burn out... live and learn..
I've read that fixing the switch contact problem is a real pain. Anyone have experience with that?
Thanks for your help. You guys rock!
