My AC clutch engages...but my ac condenser fan does not turn on...and its not blowing cold air inside the vehicle
SOURCE: ac does not blow cold at idle... ac condenser fan
that seems to be the problem. If the fan does not turn on when the a/c is turned on it could be a fuse, relay, control box, or just a bad fan. Try connecting the fan directly to see if it works. Does this car have 2 fans? normally all the small cars have 2 fans one for the engine cooling and one to assist the first when the a/c is turned on. Without the fan pulling air through the a/c condensor the had pressure goes up high enough to shut off the a/c compressor. It also causes some cars to run warmer than usual when stopped. Check the a/c condensor for blockage also which doesn't have anything to do with your fan not working.

This could mean you need a refrigerant recharge, that you have a refrigerant leak, OR that the mixer valve is not working and that you're getting hot air from the heater core instead of the air conditioner.
The refrigerant is probably the quickest and cheapest fix. Take it to a local shop that does air conditioner work and have them test the refrigerant pressure (in psi). They'll be able to tell you if that will fix the problem.
Don't try to DIY and just buy a can of refrigerant as you can potentially over fill the system.

105 psi? If so that is way to hi...especially for a mid-sized car. You ideally want you pressure to be between 40-50 psi. If you pressure is that hi you might have blown the pressure valve on you compressor, which is not a part that is sold seperately. You should take your car to your local Pep Boys and have them run a A/C diagnostic which runs around $45 to give you an better idea. If you don't know what you're doinf the A/C system is not something you want to play a guessing game with. Especially since it's illegal to work on it without the proper tools and licenses.

you'd replace the whole pump, but check to see if there is any power from the plug on the ac pump before doing anything. If there's power it should atleast make an attempt to work.
