I have a 89 lx and i can only get the defrost to work, it will not blow on floor,vent etc. i just put a blower motor in and i have checked the vacuum line to the vacuum motor and that works fine, could it be the switch that the vacuum and power plug into? it's called the damper door switch. it's the part that goes on behind the selecter knob.
hope some has a answer confused
:headscratch:

the damper door switch is what switches between floor, vent and defrost-so I would replace that next if all of the vacuum connections are good. there should be a few of them(vacuum conn.) under the dash.
