AC not working

Tellmee · 06-09-2019, 01:13 PM

My AC is not blowing cold air... I have taken it to local mechanic and also the dealership. Apparently, there is basically nothing wrong physically but the computer is not getting correct reading on my pressure sensor even though the sensor is not broken. I have read that some people had same issue and fixed it by flashing or coding so that the module communicates again with the sensor. Has anyone experience this or have any insight on how to fix it or can code/flash it?
Thank you.

I had a strange issue with my AC not working at all. You might want to check the fuses.

The signal originates from the hvac panel
