Jay :

Hello and Thank you for using JustAnswer.com

Jay :

All Blower speeds are not working?

Customer:

Blower speeds are displayed on screen. But blower is not on. It does come on finally after a period of time.

Customer:

Blower speeds do work when fan finally does come on.

Jay :

Ok

Jay :

Your going to need what they call the Unified meter / AC control amp.

Jay :

That is what controls Blower Speed operation.

Jay :

Do you have Intelligent cruise control?

Customer:

No, it does not have the technology package. I believe it is just normal cruise.

Jay :

Ok, just wanted to be sure, cause the Unified Meter / AC control unit gets calibrated when the Intelligent Cruise Control recall is done

Jay :

So you will need to have that replaced. It's located under the radio.

Customer:

We have an extended warranty. I assume that will be covered. We purchased from a Nissan dealer in Denver, Will they know what you are talking about?

Jay :

They should

Jay :

All Nissan Dealers have access to the Service Manuals to your car to perform the proper diagnostics

Customer:

Just to clarify, the fan should turn on anytime you want it to, right? Just turn it on and it should blow immediately?

Jay :

If you want to manually control the fan, yes it should operate

Customer:

Ok, it acts the same in manual or auto mode.

Jay :

Yeah, so you are going to need that Unified Meter / Ac control amp

Customer:

Great, hope that works and makes momma happy.

Jay :

Well, it will make Momma comfortable again when driving in her FX

Jay :

:)

Customer:

Thanks Jay, I see your point.... that's a big plus though. Thanks alot

Jay :

Your welcome, and have a happy holiday.

Jay :

Thanks Jay!
