Re: No A/C compressor ground relay signal
Ok, replaced the PCM with the same year, same part number but this one has a slightly different operating system & would not accept my tune file. I had to change all the parameters manually. Now the AC works as it's supposed to & no more solenoid clicking, BUT the fan that comes on with the AC, now runs anytime the engine is running!
It has to be a programming issue, but I haven't found it so far. Anyone have an idea what I did wrong?
