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?

johnnyv8

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.

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....
