Default Recharging the CFI's

The coolant in my 2003 PT Cruiser is low and the AC is cranking out warm to hot air with the AC controls set as high as they can be. I have an 'AC Pro' recharging kit with gage and quick disconnect but cannot seem to find the Low Pressure charging port to hook it up. Does anyone know where this port is to be found? I have viewed DIY recharging videos on YouTube but none that I've found are PT's. HELP!

Before you charge it, verify it has no charge, you can rent an AC manifold gauge or buy one for like $30, there a lot better then the ones that come with a can. Or push in the low pressure valve with a screw driver to see if anything comes out.
If it has a charge don't add more, check that the rad fan Assembly functions, the AC will turn on then off if it doesn't work, giving hot air. Also check the pressure switch ontop of the dryer, I had mine go bad last summer.

Check the condition of the AC clutch, after a harsh winter last year mine separated into two peices!

If your going to charge it, make sure it has a dye inside the refrigerant that way you can tell where it leaks out.

Good luck with your repair! Nothing feels better then cold AC!

I would return that AC pro kit and just Have a shop do it. Most shops have AC service specials this time of year. You will never get it as cold as a shop because they vacuum the moisture out of the lines and then refill it to the correct level with an accurate gauge. A local shop here got my AC 12 degrees colder Than I could get it. I'm never fiddling with those cans again, there is nothing pro about it.

AC Pro kit has the air pumping out of the vents at 40 degrees this morning. I'm plenty satisfied with this result and the just over $50.00 price including the thermometer and tax. I thank all for their input. This is a great group. This problem has always cost hundreds to fix each time I had to take one of our PT's in for service.
