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.
