Default A/C issue

Just wanting some more advice as usual, first time I have tried to use ac since I bought and of course nothing but hot air. I started out by testing the relay and all good, then I used an old pressure gauge I had from a previous fill up on my last car, and it read 0. So I proceeded to put a can (26 oz) in and now the compressor will engage but the air is still quite warm. Do you think another can is in order or would I be wasting money and should look elsewhere? Thank you for any advice.

Majority of the time when your a/c isn't working/not cold it is due to a loss of freon. You could try another can, but you'd be better off with a proper a/c system charge at a shop. The cans push air into the system where as a proper charge uses a vacuum.

I also forgot to mention that the ac compressor is turning on and the pressure appears to be holding steady from when I put the can in....thanks

If you start out warm, there's a leak somewhere. You are just wasting money and time if you plan on keeping the car longer than 1 summer.

I would suggest getting it to a shop where they can add chemical with dye and see where the leak is.

Also be careful with the cans, you can over-fill easily and possibly damage the system, or accidentally buy some with stop-leak built in and damage components

I agree with Leprechaun and Chibi.
The most common leak is from the compressor at the shaft seal. Not worth trying to fix the leak, just replace the compressor, but to do it properly the accumilator and orifices need to replaced too and the system flushed. You can buy the dye with UV light pen and glasses from the parts store to detect the leak, but then you need to put the system under vacuum with a vacuum pump, weigh the proper amount of 134A refrigerant to add and use a hi-lo HVAC pressure gauge set to get the correct charge. I did my own with help from my HVAC buddies, but considerable know how and equipment is required.

Here's a general idea of the kit: http://www.ebay.com/itm/2000-2003-CH...wbfnBg&vxp=mtr

My last leak was a crack in the condensor that I would have never found. Luckily I left this one to the pros.

The way that our air dam deflects air, sometimes other stuff can be deflected up and hit parts.

Thanks for all the input, sounds like a trio to the shop will be in order then. Which is unfortunately more than I can do now...so we will see.
