97 seat wiring help!!!

well i used the factory hot wire from the lumbar/whatever motors to hook up heated seats. It didwork, no fuses blownfor about 2 days?. However today it didnt workon both sides. i unpluged one side and hit it with a test light and no power... scratched my head and pluged it back in... for good measure i tried it again and both worked....... wth??? my wore splice is good. i soldered and heat shrunk it...... so what can be going wrong??????? it doesnt make sence

yes i believe. i used the factory ground wire than runs up. should i ground it out to the frame and try? im just really confused because it doesnt blow a fuse, however doesnt work. i would trace the wires but they are under the carpet
