Wierd a/c issues

[MIKEP89]

My a/c has been acting pretty weird is has been running like its low on freon but no leak. It blows colder at a stand still than moving. The only thing i can think is maybe a restriction somwhere on it maybe orifice tube or something?
Any ideas

What are your pressures like (low and high side?)

Could be the clutch going out, or the system isn't sending the signal to activate the clutch regularly, which may explain why it works at lower (idle) rpm and not while under way, but the place to start is to check your pressure like Lester asked

I've been having AC issues too. Sometimes it won't turn on unless I smack the bottom of the AC vent, the black housing just above the "passengers feet area". Thinking it's an electrical issue..?
