The rear fan control switch on the control module is broken and will not engage with the internal switch. The knob just spins. I took the unit apart and found that thier is a plastic unit which attaches to the internal switch that is broken. Unfortunatley the dealer doesn't sell this piece and requires the customer to purchase the entire control module at a whooping price of $300.00 . Anyone expirenece this problem? Is there a fix other then purchasing a new control module? I have a video on youtube " nissan armada 2004 faulty control module" which will show you what I mean.
