No AC after fw 3.3.1a (?)
#19
Not thread jacking, but since we have similar issues (exactly the same but opposite, my AC gets stuck on) I figure we can see what similarities we find. For me, I just found that my AC will not turn on, but once the car hits operating temperature, it is then stuck on. Disabling the PA0 circuit for me turns off the AC compressor; however, once I enable it, the compressor stays on regardless of which way the button is pressed on the dash. Likewise, once the compressor turns on (when PA0 is enabled), going back and disabling PA0 does nothing; the compressor remains on. I also found if I play with the thermoresistor values to lower the perceived CLT temp, I can turn my AC on or off. Because of this, I think it's safe to say we are having an ECU issue.
*edit* I found a solution that seems to work well for me. See the following: https://www.miataturbo.net/megasquir...2/#post1092765
