I have an 84 that I just replaced the blower motor on a a week ago. It worked fine for a couple of days then last weekend I couldn't get the switch to turn it on. The fuse is fine, the new motor is fine. I tore apart the dash to try to take out the air control unit and when I was moving it around in the dash I had the key on and the blower kicked on. I checked the diaphram also and notices that it wasn't moving when I was sliding the bottom knob. I really need a quick fix to get me through the workweek and until I get paid. Any ideas?
