Hi, I was driving home last night from a road trip and noticed a shift in where my air was coming from. I went on climate settings and the ac light was flashing. Today I checked the code initially it was 19, I changed the cabin temp sensor and rechecked the code. Now I get a 00 with the same issue. It sounds like the compressor kicks on for a second or two makes a noise and shuts off and the ac light begins to flash.
