Hey guys, yesterday was the first day in the high 80's in Jersey. I went to put on the AC in the stang and guess what? No cold air... I can also tell the ac not kicking in cuz the car not as slow if you know what i mean. I cant see the tune messing it up, just figured I throw the idea out there.

its 06 GT w/ 40k miles (no warr left)

 

I hafta ask a silly question....Was the temperature control in the COLD position?
Also, did you try turning on the A/C using both methods, i.e., selecting VENT and pressing the A/C button, and also selecting MAX A/C?

 

Do you have underdrive pulleys?

 

No, I dont not have ud pulleys

and yes, I tired all the turning on ac both ways, and yes, it was on cold, lol. kinda sucks, this car has been really good so far.

 

I live in hot and sunny Florida and a Mustang a/c will usually freeze you out even on the hottest days. You probably just need a recharge that you can easily do yourself. Just go to Auto Zone or Advance Auto and get a kit with gauges (so you don't add too little or too much) and do it yourself. Get the refrigerant that has the sealer in it in case you have a slight leak. It's very easy to do and the good kits are usually less than $30.00 for everything.

 

The CCM and the PCM are two different spanish oak
units running independently of each other, so did
your tune cause your AC to quit working, thats a no.

 

You have too much air in your tires or your radio has stations preset to country music. If those don't work, replace the muffler bearings.

 

Dang...that's funny right there ^

 

get the system pressures checked, no doubt you are low on r134a.

 

Definately a NO to your..."Tune maybe" ? question .
You most likely need a system check and a re-charge....
