1990 Nissan 300ZX Question: heater door

heater vent that opens and close to allow heat in the interior of the car doesn't work. How do I replace it? Where can I find the part? Thanks -
Answer 1
You should get the repair manual from the dealer and the part too, I don't see any other source for the part. -
Answer 2
If you mean the ducts that have louvers on them that fit into the dash they are only available at the dealer or a wrecking yard.If the problem is heater not flowing correctly there are three motors behind the dash that operate the blend doors in the heating and air conditioning housing. -
