Warm Air AC

Howdy Again !
The AC has been blowing warm air
So I tried changing the $17 fuses in the engine compartment , and when it didn’t activate the othe belt , took it back to the store and refunded it .
then I got the Frion , found out that it’s been real low in the car all along , so I filled it up to the top green level .
Now that activated the belt !
thou the air it still WARM

It is pretty HOT here in Carolinas , would be nice to have the COLD AC running !

Any suggestions ?

Yep. I’d suggest not relying on the pressure gauge to know how much refrigerant is needed. Also, if there was no cooling before, all of the refrigerant may have leaked out and moisture may have got into the system. If so, a top-off like you did isn’t going to help. The system probably needs a full vacuum draw-down to get rid of the moisture, followed by a proper refill with a known amount.

Also, test the operation of the Dual Climate Control Valve (DCCV). It has a very high failure rate and could be dumping heat into the cabin and overwhelm the AC portion of the system.

Long-winded troubleshooting guide here. Lots to digest, but please follow the steps in order and it should lead you to a correct diagnosis:

It’s possible you’ve got more than one fault in play. After you find and fix one, repeat the troubleshooting from the beginning to find the next fault.
