i got a 77 chevy truck that is my girlfriends but i take care of it now. her dad took care of it before me and he jerry-rigged just about everything. The blower motor doesnt work and i thot it was the the switch so i replaced it b/c the high setting was screwed up when i tested it. it still didnt work. the blower motor is also new b/c the old one rattled a lot. should thier be anything between the switch and the blower motor besides the resistor? i am totally stumped on this and am about to just run a wire from the fuse box straight to the blower but thats my last resort. Any ideas before i try to tear the dash apart?
