heater blower

[Beany-s12]

the heater blower hasn't worked in my car since buyin it and thought while its off the road i'd look at it! motor is fine as i've got it bridged to run perminant at mo and previous owner reckons it worked fine until he took out the dash and refitted it! car used to have aircon which has all been disconnected so don't know if thats any thing to do with it!
if not any help with positions of resistors or wiring blocks or common faults i might've missed? any help gratefully recieved thanks as don't think having the blower on full all the time is good for it
