ac/heater blower fan not working - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I did a search, and went back 22 pages.

Like title says, ac/heater blower fan not working at any speed.

When I had a maxima, my blower fan sudden only worked on the fastest speed. Replace the resistor and it fixed the problem.

Is it the same fix here?

thanks for any help.

Nope. A bad resistor would give you full speed fan only, but not lower speeds. I'd say it's the blower motor itself, unplug and check for both power and ground. Remember the ground is variable through the resistor so check it at each speed setting. If so the motor drops out with three screws.
