Ac not working

My ac only blows cold on the highway. I just got it charged about 2 weeks ago.

Is your condenser all plugged up with crap restricting too much air flow at low speeds? That's my best guess with this little info. Did you have a shop charge it or did you do it from one of those recharge cans?

99 Wrangler Sahara 5spd manual - Mine
08 Patriot sport 4x4 auto - Wifes
92 Cherokee Lorado auto - for when mine needs fixin/winter beater

Im sorry, some times i drink and post stupid comments.

The gauges all reading a little high with the charge they put in. It might be freezing up like you said

It shouldn't freeze up from an overcharged system, this usually happens on an undercharge. How much over are the pressures? Your compressor is most likely weak, especially if the low side is high at idle, say 50psi or more. Look at the low side line it should be sweating, if not your overcharged or your compressor is shot.
