My A/C started making a hissing noise and then started blowing warm on the driver’s side and now it doesn’t blow cold at all. Any suggestions on what could be wrong?

Hi,

If you noticed loss of cold air on the driver's side, but it still worked on the passenger's side, it sounds like there could be an issue with the mode door actuator.

When you first turn on the AC, do you hear the AC compressor click on? Let me know that. Also, let me know if you still hear the hissing noise.

Take a look through this link and let me know if it helps:

Let me know.
