I hook up a gauge from autozone to see the pressure and it says its filled but my ac is still blowing hot what should I do?

Clarification: When you say gauge, were you monitoring both the high and low side pressures? If so, what were they? (And what was the ambient temperature outside?)
Does the compressor turn on? Is the condenser old because it could be clogged also.
@Bobsampson can you copy and paste your answer into the ‘Your Answer’ box down below? I was only using this for clarification to the OP, whereas yours was more of an answer/troubleshooting. Thank you.
Its clicking on and off the compressor
just low side
You can't tell anything from that, least of all if your AC system is "filled".
You need to hook up a proper manifold gauge set and check the system pressures while it is operating. (Assuming the compressor is turning on.)
