Ok I recently put in a radio everything was working fine. Now I noticed my climate control module does not turn on at all. I checked fuses and cant find any blown. Is there a specific fuse for this? I ordered another module just to check if not I'll send it back. Any suggestions? help would be appreciated!!!

 

any help appreciated guys

 

Is it the screen not lighting up or the buttons do not work or both? Most common cause is something not hooked back up when everything is put back together. Did you take it back apart to see if one of the plugs did not seat all the way?

 

the screen lights up but the module itself seems to not work like its not getting any power, no functions work at all and no buttons light up the plug behind the module is connected. I will be trying another unit today just for the hell of it.

 

Ok switched out unit still nothing. Im going to recheck fuses again. There are only 3 boxes where fuses can be located am I correct? What else can this be???

 

rechecked all 3 fuse box locations no blown fuses could a relay have gone out? or are there fuses I'm missing?

 

Does anything else not work? Its late. Ill run though the wiring diagrams in the FSM tomorrow if i get off work at a decent hour. The three fuse panels are under the dash, by the battery, and by the windshield washer bottle under the beauty cover.

 

Yes everything else works but the climate control module. It seems to not be getting any power to it. All fuses seem to be fine. I even switched out the module itself still nothing. Could the unified box be bad? there were no coins or any sounds coming from it. This thing is a real pain thank god I havnt got caught in bad weather, with no air controls that will be pleasant.

 

Might just end up having to take everything apart and bring it to nissan like that so get the cheapest diag time I could possibly get lol

 

Same thing happend to me a few week ago in my 6thgen except I had no radio and my fan was blowing. It's going to be hard to determine what the problem is unless you diagnose it. Electrical is one of if not the most stressful issues you can deal with on your car. Mine just started working again on it's own. Try unplugging the battery for a little bit. It's a gamble.

 

Yea wouldnt hurt to try. I just want to get this figured out already I might be heading to Nissan today!!!

 

Yeah. Try unplugging the battery for a few mins and maybe you might get lucky and it will start working again. If I was you I would try to find a good local mechanic because unlike the stealership he might be able to tell you what's wrong without charging you a diagnostic fee. Get a refferal for a mechanic who specializes in nissan cars. The stealership should be your last option unless you're loaded. Good luck though.

 

Tried disconnecting battery still nothing. Nissan quoted $110 Diag which is rediculous so I'll try the local mechanic!!!

 

Yup. When it comes to electrical there's very little you can do and you will most likely have to get the diagnosed. The dealer is a fixed price but you can find a local dealer who's just as experienced as the stealership except he would do it for half the cost.

 

Recheck that everything is plugged in. Ive done it a time or two myself. If its anything worse, I have an extra center section laying around. (Heater cont, radio, screen, etc.)

 

Hey yea I made sure everything is connected and even changed out the module itself and theres still nothing. All I know is theres no power going to the module itself. Its pretty damn hot here in FL so I must get this fixed asap!!!!!

 

Still havent found anything new Im thinking its the white unified box behind center dash that might be the problem!!!!

 

any help is appreciated!!!!!

 

going to try swapping out the unified meter box see if that helps if not send it back.

 

turns out the connector from unified box was bad I swapped out the box itself and behold all works.

 

where is the unified box located exactly? and where did you get your replacement part? i am having the exact same problem as described in your post after a radio install.

 

The unified box is right under/behind the factory radio. It has a connector going to the climate control buttons. I got my part off ebay for $100 bucks which beat paying nissan to diagnose for that price and not fix anything.

 

My radio dash and doesnt light up dash works fine but radio display doesnt light up or work and my ac cintrols dont work they blow high all the time please help

 

What is the name of this part? I have a 2003 murano with the same issue center console turns on, air is constantly blowing a lo stream of air at 75 but you can't control the air or the radio

 

any updates on everyone having issues with climate control always on high and doesnt shut off...and the radio only lighs up but no display

 

bumpp someone help

 

I have the exact same problem you had where I replaced the stereo and it stopped working. Can you tell me what the part name is for the unified box is? And do i also have to purchase the connector for it?

 

I’m trying to have a new radio installed in my Nissan Almera 2004 and cannot get an ISO harness to fit my car! I’ve now been informed that if I put manage to put in a new radio, the climate control won’t work! So I think that’s what’s happened to you.

 

the radio and the climate control unit share a common shaped plug and you may have them switched around. Swap them b4 you do anything else.

 

I'm having the same issue. All of a sudden my climate control stopped working. The dials don't do anything there are no lights the buttons don't do anything. My blower is blowing one speed. Any suggestions would help. I'm about to dig in behind it it does not look as though the fuse is bad. So I'm hoping there is something with the harness behind the unit itself. Incidentally I saw another post that there were issues with the radio thus far I have had none nor have I replaced it.

 

I have 2004 Nissan Maxima, and my A/C is blowing, and the controls don't work but they do light up and screen don't come show anything now. I went to the junk yard and picked up unified box but it didn't work. It does the same thing as the other one. Can someone help me please.

Thank you

what and where is the unified box? I’m having the same issue. I’ve swapped the climate control out three times. Thanks

 

Check your ground! You might have lost your AC ground when you instilled your radio! Make sure you're ac has a ground. Good luck 👍

 

my controls light up and stay on but can't change anything since shop changed radio and removed monitor screen and old radio what can it be already bought for climate control modules and they all do the same thing turn on stays on and can't change the controls
