Hello, so I'm pretty good at fixing things but not diagnosing them. At one point my air conditioning was working great and then I heard a pop when I was using it. The snowflake flashed usually representing low Freon. The Freon checkout out a little high but definitely not low. The car only blows cool air when I'm driving pretty fast. Its not enough to even cool off the car. Both fans are working, the clutch is kicking in, and its coolant is fine. Can anyone give me some ideas as to where to start troubleshooting?
If it's overcharged you could be killing the compressor to much freon is not a good thing on a pressured system
Are you saying the air coming out of the vents is not cold unless you are moving ? Or there is no air unless you are moving ?
And are you sure the radiator fan is running with the ac on ? Can you feel air being pulled thru the condenser ? What are the gauge readings with the ac on and the engine at idle ?
Testimonial: "air comes out when i turn it on (moving or not) and yes i'm sure the fan is coming on. it was off prior to the ac being on and as soon as i turned it on the fan went on. The tac reads at just over 1000 rpm before the ac is on and the just below 1000 rpm after it kicks in. (is that which gauge you are talking about?) and yes I can feel the air being pulled through the condenser. The only other thing that i really noticed was that as my fan strength gets turned to 3 or 4 I hear a slight pulsating sound. Not sure if the pertains to anything."

How did you check the freon charge ? Thats the gauges I was talking about. The high side should be around 200psi and the low side should be around 35psi at idle if the freon charge is ok and the system is working.

SOURCE: air conditioning compressor will not kick in,
If it is above 100PSI, you are over charged. Any thing under, should be normal to low. You probably need to get it checked by a professional to make sure it has the correct charge, and the compressor is getting power when the switch is turned on.
SOURCE: Problem with air conditioning on 2001 mitsubishi mirage.
the air conditioning system has most likely drawn moisture this is not good take it to have the system recovered and a new restrictor valve put in. leak checked and recharged
SOURCE: A/C blowing hot air while driving
Could be a vacuum line is busted. When you apply brakes it provides pressure to the system for freon to move and blow cold. Without that forced pressure freons not moving. I had that problem with a ford f150 and finding the busted vacuum line fixed it. It may be different with a mitsubishi, ask a local mechanic

check the refrigerant it might have 2 be recharged

Could be a blockage. Get an air-con specialist to blow the lines out. Check for any leaks from the rubber pipes. The twisting nature of AC pipes in cars can perish and if you have heard a blow out (like a tire blowout) the air con might have blown through a pipe.
Any leaves trapped in the windshield/hood gutter?
