heater controls?

Just move the cables around and note which cable moves when it goes from/to a function! Then, go to the heater box and identify which door operate which function! The defroster block off is easy to spot as the vents come out the front! The heat/cool block off door either brings in heat from the heater core chamber, or the vent where the fresh air door also gets its air!

Its pretty easy to trace a non A/C car system!! You can do it I'm sure!! Geof
