Either a vacuum leak because of position problems or blower motor resistor because of speed issues.

When it does work all the position work and the controls to go from defrost to foot and both upper and power from low to high also work fine so i guess i should should look at the resistor for the blower itself...?

had the same problem, untill yesterday. when i sat in the truck and turned the key on to wait for my fuel prime my fan was blowing on the lowest setting, then when i cranked up the thing just stopped. now i cant get it to work at all so im going to replace the relay and resistor just because they are old, maybe the motor too but that thing was blowing strong as hell last time i took it out about a year ago. just moved to va from florida though, everything seems to be different with my truck up here in the cold. i got some of that sweet bright red spectre vacuum line i think it is, from summit. at like neg 10 deg its still flexible as all get out, so im still working getting all my lines replaced with this stuff. will update later
