Freon overcharge

My girlfriends 2005 Scion TC was blowing hotter than normal air so I hooked up one of those Freon 134A kits you get from Auto Zone and followed the instructions. After running it for a little bit I noticed the air isn't any cooler, rather it's warmer. I hooked up the gauge to it and now the pressure is in the "warning" range of 70 - 75 and the compressor is turning on and off more frequent than before. Is there an easy to take "discharge" the excess freon I put in there? Do I need to take her car to a mechanic?

Thanks in advance.

the pressure goes that high when the comp turns off, its more than likely your drier is clogged

What should I do to fix the drier? Also, what exactly is the drier and what does it do?

driers just get replaced no fixing.

So how do I remove the excess freon I put in there? Even if I replace the AC drier, there will be to much freon still right?

if you replace the drier you will have no freon left as it will all evacuate the system.

Need to see high and low side pressures to see what is really going on just saying a blockage in the drier aint helping anyone just take it to a shop unless you wanna invest in some tools

could be orifice tube, in addition to or in place of the drier.

You need to fix the problem and likely have the system vac'd down and re filled. at this point i would just take it to a trust worthy shop

you actually CAN fix a dryer
it uses silica to draw moisture from the coolant, which you get when there is a leak and pressure drops too low

to fix it put it in the oven at 250 for a few hours

edit: you should take it to a shop and get them to replace the can and draw/fill the freon

I'll just add that R-134a isn't Freon.

wwilliam the problem is the oil in the drier that will not evaporate, and its always good to replace that, and its just easier since most shops dont have an oven for fixing driers its better to just replace them.

also if there is anything in the drier like metal bits or anything else an oven will not take care of that.

There's a reason why the tools and machines shops use to charge/fix AC systems are so much more advanced than the cheap R134a kits you can buy.
