I have a 1990 300ZX and the recirculation door for cooling and heating is not working. When I push the recirculate button, the light lights up so I assume the switch is working. Where is the door and how do I get to it to fix it. I’m guessing it is somehow jammed.

This is one of those times when having a service manual comes in REALLY handy. A service manual would have step-by-step instructions for diagnosing and repairing this problem.

Factory manuals are always best, but something like a Haynes manual often works quite well for much less money.
