AC problem blowing hot air HELP!!
 

I recently did a Double Din install and am now having problems with my AC. It will only blow cold air when I turn the temp down to 60 degrees. Anything above that blows hot air. I have checked the connection under the steering wheel and that is fine. What else could be the problem? PLEASE HELP!

Thanks!

Do you have a Z-tube?

If so, read this.... https://g35driver.com/forums/intake-...e-ac-line.html

if you look at the panel underneath your steering wheel, there's a plug not plugged in right above the rubber hose. it's on the right hand side... you should try searching around the technical section, this was covered couple times~

K@osk71 - as I mentioned in my initial post, I have checked the sensor connection under the steering wheel and it is connected properly and I am still having the problem. Any other suggestions?

Thanks!

Do you have a z-tube or any other aftermarket intake tube? if you do and didnt tie it with a zip tie or put some type of material in between it probably made a hole in the AC line. Check there.

As silly as it sounds, did you ck ur A/C belt? It happened to me.

i have the same problem...i have an 04 6mt with jwt pop charger....60 degrees= iced cold, anything above that, it's hot (61+ degrees). didnt get it fix, still need help, i will check the a/c lines

Remove the bottom panel underneath your steering wheel. There is a white plug located on the backside of the panel. There is a black rubber tube that should be connected to this white plug.
If its not attached, your AC will blow cold only at 60F, anything above 60F, the air will be warm.

This happened to me when I installed a DD head unit. The tube got stuck up inside...it was a bit** to get out but I managed to get my hand in there.

thank, will try that...ill let you know how it goes

thanks alot bro!!! it was exactly what you said it was, the white plug. my ac works perfect. you saved me some money! thanks again

No problem...glad I could help out.

My check is in the mail right?????;)

Where is this white plug that you are referring to? I took the panel off under the steering wheel and don't see it. Thanks for your help.

See this thread:

Next to the black hose, it is right beside the center console. If you look at the panel you will see(I think its 4) lines and a hard, shiny plastic piece and the hose and clip should go right behind there.

thank you, I will check it out this week and let you know how I made out!

AC blowing hot air with compressor in gagging
 

Hi ac blowing hot air because the compressor wasn't in gagging the Mecanico give voltage with a manual switch and I had cold air. Now with the compressor on ac is blowing hot air help me please.

New compressor last year
 

Leaked out all your refrigerant.

So I cud possibly need sum refrigerant

If you lost it that quickly I suspect there's a leak somewhere that needs to be fixed. Don't need that **** leaking into the air we breath

Take it down to an auto AC shop and have them pump it up with nitrogen and find the leak, fix the leak, recharge the system. If your system is completely empty DO NOT just use bottles of AC PRO or other recharge cans, you get a really bad mix of refrigerant and oil and most of them have stopleak which is really bad for the rest of the system. Using that crap in large volumes is a guaranteed way to cook your compressor within a few years.

If this is just a disposable vehicle that you're getting rid of soon then I guess it wouldn't matter and you can limp through a couple years though.

Nothing wrong with using AC PRO to top a system off yearly if you're only down a few psi.

Thanx... Im gonna get it chkd out... But I can't really tell if the AC is coming on... It sez it on the dash but I do not hear the engine go down or any change 2 the engine when I cut the AC on. How can I tell if it is coming on besides the dash?

Best way is to open the hood and have someone else hit the AC button while you stand at the engine and listen for the audible CLICK sound from the compressor cycling on and off.

Thanx...
So if there isn't an audible click that means it's not coming on & compressor is dead?

It just means the compressor is not cycling on, some vehicles the low pressure switch will 100% prevent engagement, some vehicles it will engage and immediately disengage. You can unplug the compressor harness and (carefully) test for voltage to see if it's even getting power.

There is also an AC relay inside the IPDM, if you remove the cover and put your finger on it you should feel the vibration from the contact opening and closing while someone operates the AC on/off with the engine running. If the contact isn't operating test it to make sure it's not broken.

There is also a master fuse for the AC located in the fusible link directly attached to the battery. You can visibly inspect it, there are viewing windows for the fuses. Also a fuse in the IPDM I believe for the control side.

On second glance, low pressure should prevent the compressor from turning on AT ALL. You're probably just low on refrigerant and need to get it inspected and fixed.

EDIT: Usually you can tell where it's leaking from because when it leaks out the oil comes out as a VERY fine mist that sticks to the pipes or components so you end up with a compressor line that's completely covered in dirt that sticks to the oil tracks.

Thanx again... I appreciate ur time
I'll chk things out but if it seems 2 complicated or ill break sumpn I'll b @ a shop... Lol

Can we sell things on here? I'm new so I have no clue.
