Ac blows cold when moving, sitting in traffic or at a light the air blows warm. Not sure what it could be. One mechanic shop states it’s the compressor but I don’t think it is because when I’m moving. It feels great. Anyone else had these issues?

 

It's probably your Direct Pressure sensor see attached TSB

 

Am about to do this repair. My AC has become horrible I got mad and did wot and it started working again so I’m thinking it’s the pressure valve. I have the fist gen AC compressor so cross reference the vin cut off from the TSB.
