I have a '89 Civic Hatch STD, no a/c, no heat, no defroster [obviously]. I was just curious, what would I need for the heater/defroster to work?

I have tried searching and can't find it, if you can give me a link or any info, please, do so.

Thank you.

 

this is a VERY generic question and should be more specific. What do you have?

these are the main parts:
climate control unit, heater box with core, heater control valve

 

honestly, i am not sure. i have the climate control, im not sure if it is connected behind the dash though. as for the heater box with core and heater control valve im not sure what those are.

 

Sounds like you have no fan..
Do the fan blow?
