Digital AC Not working after remote start install

[HybridAlti]

Hi All,

I recently had a remote start system w/keyless entry installed on my car. I own a 2010 Altima Hybrid with the auto ac, it has the digital ac controls

My AC ranges from 60 to 90 Farenheit
Ever since the install it only blows cold air when it's on 60 or 61.
From 62-90 it blows hot air, the level of hot doesn't increase at all, it's just hot, it doesn't go from warm to hot

Has anyone ever seen anything like this?

I have tried to run a self diagnosis check on the cars ac using the procedures outlined in the attached document.
I tried running the diagnosis in section HAC-23, "WITH LEFT AND RIGHT VENTILATION TEMPERATURE
SEPARATELY CONTROL SYSTEM : Diagnosis Description".

Yet I am not able to start diagnosis, I follow all the steps and never get any indication on either the AC controls or the tachometer display. I turn on the car, the engine starts in about 3 seconds since its a hybrid it takes a bit to need the engine, then I hold the OFF button for 5 sec and no notification of diagnosis is evident

This is the remote system that was installed: http://www.compustar.com/remote-starter ... -S-KIT.php

I don't think it has to do with freon or the compressor, since when on 60-61 it blows cold air really well and really cool. The blower speed also works.

Should be:
60-70 Cold
71-80 Mix of hot & cold
80-90 Hot

What it is:
60-61 Cold
62-90 Hot

to NICO!

Assuming you had the remote start installed somewhere, I'd certainly take it back and see what they say. I'm guessing they left something disconnected - spliced in to a wrong wire, etc.

Check out http://www.nissanservicemanual.com for the full FSM - there may be more diagnostic ideas there.

Good luck!

So I took it back and first the guy there didn't seem to want to work on it. He just said to take it to another location where I got the work done, I explained that I bought the system from their store and I would think they have the same installation procedure as any other store on the same car. He just didn't want to work on it or look at another guys wire job. Oh well not my problem since their work is lifetime guaranteed and this is part of what it includes, Like I always say, sometimes you just gotta make people work, specially if they're at their job, I mean come on.

So he couldn't understand why I wasn't happy that it blew cold at 60-61 and hot in any other setting, after explaining that it should be warm in the middle and that generally 65 in a car should be closer to cold rather than hot just like in a house thermometer I think he got it, maybe.

Well I get a call about 3 hrs later that they found what it was maybe.

The In-vehicle sensor was disconnected and this was throwing everything off.


The AC works like normal again.

Glad you got it fixed! and yeah, sometimes warranty can work wonders.
