Help resolving ac

Sorry yea another ac question, I need help fixing it, I have searched, my ac works, sometimes, at night works the best, when on the high way it kind of works, and it doesn't work at all the is not moving. Clutch engages, and I see aux fan working but I haven't checked relays... which one should I check again, could it be an incorrect charge? Incorrect Freon?

If it was working previously and you haven't added any Freon it can't be the wrong kind.

Poor cold air output is almost always a sign the system is low on Freon. It won't be too long before it stops cycling the compressor. There is a high/low pressure switch in the line. If it gets too low it will prevent the compressor from engaging. Likewise if someone has "topped it off" and added too much the switch will keep the system from running because there's a risk of over pressurizing the system, causing damage to the compressor.

Get it checked by a pro. Unless you have an A/C gauge set and KNOW HOW TO USE THEM, you can't accurately judge the system pressure. A/C systems are the one area I don't usually mess with, even though I have all the equipment to service the system and know how to use them.
