Im working on a 94 mazda b2300. I got it with no heat working, finally got all cables situated and no matter what i try i cant get air to blow from defrost vents.
It is all cable operated, no vacuum and no electric motor for blend door.

It does have a bad blower motor resistor, so air only blows on high but i couldnt imagine that would effect defrost.

A\C and heat both work great.

Thanks in advance for any help
 
Is the blend door broken, or is the ducting to the defrost vent broken?
