your description is a little confusing. are you saying the blowermotor for the heater/air inside the car under glove box? and when you run hot wire to speed resistors everything works normally? you could loosen fuse box and look behind it for burnt out connection? also the control button assembly on dash for burnt wire/connector. turns out if fan is run on high too much these things are known to fail/melt!
